Case Study - 2

Case Study - 3

Based on the above information, answer the following questions:

Q1: Find the production during first year. Ans: We are given that the production of TV sets in the factory is increasing uniformly. This means that we can apply the formula of an arithmetic progression, where the nth term (a_n) is given by a + (n-1)d. Here, 'a' is the first term, 'n' is the term number, and 'd' is the common difference. We know that the 6th year production (a_6) is 16000 and the 9th year production (a_9) is 22600. We can subtract the 6th year production from the 9th year to find the total increase over 3 years, which is 6600. This means that the common difference ('d') is 6600/3 = 2200 sets per year. Substituting the values into the nth term formula: 16000 = a + (6-1)*2200 16000 = a + 11000 => a = 16000 - 11000 => a = 5000 So, the production during the first year was 5000 sets.   Q2: Find the production during 8th year. Ans: We can use the nth term formula again to find the production in the 8th year. a_8 = a + (8-1)*d = 5000 + 7*2200 = 5000 + 15400 = 20400 So, the production during the 8th year was 20400 sets.   Q3: Find the production during first 3 years. Ans:  To find the total production over the first 3 years, we sum the production over each year. In an arithmetic progression, the sum of the first n terms (S_n) is given by n/2 * (2a + (n-1)d). S_3 = 3/2 * (2*5000 + (3-1)*2200) = 1.5 * (10000 + 4400) = 1.5 * 14400 = 21600 So, the total production during the first 3 years was 21600 sets.   Q4: In which year, the production is Rs 29,200. Ans: To find the year when the production was 29200, we can use the nth term formula and solve for n. 29200 = 5000 + (n-1)2200 => 24200 = (n-1)2200 => n-1 = 24200/2200 => n-1 = 11 => n = 12 So, the production was 29200 sets in the 12th year.   Q5: Find the difference of the production during 7th year and 4th year. Ans: We can find the production in the 7th and 4th years using the nth term formula, and then subtract the two. a_7 = 5000 + 6*2200 = 18200 a_4 = 5000 + 3*2200 = 11600 Difference = a_7 - a_4 = 18200 - 11600 = 6600 So, the difference in production between the 7th and 4th years was 6600 sets.

Three lines shown in the figures intersect each other at point P. Line l is perpendicular to line n. The measure of ∠2 is 65°.

Q. 1. What is the measure of ∠6? (a) 30° (b) 45° (c) 25° (d) 60°

Ans. Option (c) is correct. Explanation: Clearly ∠2 + ∠3 = 90° (as l is perpendicular to n ) ⇒ 65° + ∠3 = 90° ⇒ ∠3 = 90° – 65° ⇒ ∠3 = 25° Now, ∠6 = ∠3 (Vertically opposite angles) ⇒ ∠6 = 25°

Q. 2. What is the sum of the measure of ∠3 and ∠4? (a) 95° (b) 115° (c) 120° (d) 155°

Ans. Option (b) is correct. Explanation: ∠2+ ∠3 + ∠4 = 180°. (Linear pair) 65° + ∠3 + ∠4 = 180° ∠3 + ∠4 = 180° – 65° ∠3 + ∠4 = 115°

Frequently Asked Questions (FAQs) on Lines and Angles Case Study

Q1: what are the different types of angles.

A1: There are several types of angles based on their measurements: Acute Angle: Less than 90° Right Angle: Exactly 90° Obtuse Angle: More than 90° but less than 180° Straight Angle: Exactly 180° Reflex Angle: More than 180° but less than 360° Complete Angle: Exactly 360°

Q2: What are complementary angles?

A2: Complementary angles are two angles whose sum is 90°. For example, if one angle measures 30°, the other angle must measure 60° to be complementary.

Q3: What are supplementary angles?

A3: Supplementary angles are two angles whose sum is 180°. For example, if one angle measures 120°, the other angle must measure 60° to be supplementary.

Q4: What is a linear pair of angles?

A4: A linear pair of angles is formed when two adjacent angles have their non-common arms in a straight line. The sum of the angles in a linear pair is always 180°.

Q5: What is the difference between parallel and intersecting lines?

A5: Parallel Lines: Two lines that are always the same distance apart and never meet, no matter how far they are extended, are called parallel lines. Intersecting Lines: Two lines that cross each other at exactly one point are called intersecting lines.

Q6: What are vertically opposite angles?

A6: Vertically opposite angles are the angles formed opposite each other when two lines intersect. These angles are always equal. For example, if two lines intersect and one angle is 70°, the vertically opposite angle will also be 70°.

Q7: How do you find the measure of an unknown angle in a triangle?

A7: The sum of the angles in any triangle is always 180°. If two angles of a triangle are known, the third angle can be found by subtracting the sum of the known angles from 180°.

Q8: Can a triangle have more than one right angle?

A8: No, a triangle cannot have more than one right angle. The sum of all angles in a triangle is 180°, and if one angle is 90°, the other two angles must together sum to 90°, leaving no room for another right angle.

Q9: Are there any online resources or tools available for practicing comparing quantities case study questions?

A9: We provide case study questions for CBSE Class 8 Maths on our  website . Students can visit the website and practice sufficient case study questions and prepare for their exams.

SCALE FACTOR

Case study:

A scale drawing of an object is the same shape at the object but a different size. The scale of a drawing is a comparison of the length used on a drawing to the length it represents. The scale is written as a ratio. The ratio of two corresponding sides in similar figures is called the scale factor

Scale factor= length in image / corresponding length in object

If one shape can become another using revising, then the shapes are similar. Hence, two shapes are similar when one can become the other after a resize, flip, slide or turn. In the photograph below showing the side view of a train engine. Scale factor is 1:200

This means that a length of 1 cm on the photograph above corresponds to a length of 200cm or 2 m, of the actual engine. The scale can also be written as the ratio of two lengths.

1. If the length of the model is 11cm, then the overall length of the engine in the photograph above, including the couplings (mechanism used to connect) is:

Answer: a)22m

2. What will affect the similarity of any two polygons?

a) They are flipped horizontally

b) They are dilated by a scale factor

c) They are translated down

d) They are not the mirror image of one another.

Answer: d)They are not the mirror image of one another

3. What is the actual width of the door if the width of the door in photograph is 0.35cm?

Answer: a)0.7m

4. If two similar triangles have a scale factor 5:3 which statement regarding the two triangles is true?

a) The ratio of their perimeters is 15:1

b) Their altitudes have a ratio 25:15

c) Their medians have a ratio 10:4

d) Their angle bisectors have a ratio 11:5

Answer: b)Their altitudes have a ratio 25:15

5. The length of AB in the given figure:

Answer: c)4cm
