Final answer:
The Pythagorean Theorem is a fundamental concept in geometry that relates the lengths of the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
Explanation:
The Pythagorean Theorem is a fundamental concept in geometry that relates the lengths of the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. The converse of the Pythagorean Theorem states that if the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides, then the triangle is a right triangle.

Step-by-step explanation:
1. 10² + 7² = x²
2. x² + 19² = 21²
x² = 21² - 19² = 80
x = √80 = 4√5
3. x² + 16² = 27²
x² = 27² - 16² = 473
4. 5.3² + 12.8² = x²
191.93 = x²
x = √191.93
5. 9² + 20² = x²
6. 31 = x + 2√(19²-17²) = x + 2·6√2 = x + 12√2
x = 31 - 12√2

inverse of squaring a number. The square root of a number, n, is a number, m, such that m2 = n. For example, 82 = 64 and (-8)2 = 64, so the square roots of 64 are 8 and -8. When just given a radical to simplify, use the principal or positive square root. Common Methods: Pick the one that works best for you! Using a Factor Tree or pairs of factors.

Figure 5.4.9: The sine of π 3 equals the cosine of π 6 and vice versa. This result should not be surprising because, as we see from Figure 5.4.9, the side opposite the angle of π 3 is also the side adjacent to π 6, so sin(π 3) and cos(π 6) are exactly the same ratio of the same two sides, √3s and 2s.
