Question

Given a right triangle with legs a, b and hypotenuse c, solve for a if b= 20 and c= 29

a 35.2

b 3

c 21

d 9

Answer 1

the answer is C. 21

Explanation:

Answer 2

C) 21

Explanation:

a² + 20² = 29² Use Pythagorean Theorem to solve for a

a² + 400 = 841 Solve for the exponents

- 400 - 400 Subtract 400 from both sides

a² = 441 Take the square root of both sides

a = 21
