A right triangle follows the Pythagorean theorem: a^2 + b^2 = c^2

Let’s work out the problems
1. 20^2 + 72^2 = 75^2
40 + 5184 = 5625
False

2. 40^2 + 74^2 = 85^2
1600 + 5476 = 7225
False

3. 45^2 + 60^2 = 75^2
2025 + 3600 = 5625
True

The correct answer is (45, 60, 75)

Find the circumference of a circle with an area of 530.93

HACTEHA [7]

A = π r^2
r^2 = A/π
r^2 = 530.93 / 3.14
r^2 = 169.08
r = 13

C = 2 π r
C = 2 (3.14)(13)
C = 81.64

answer
