Question

2. What is the length of
side c? Someone help

Answer 1

Side c has a length of √145, or approximately 12.04.

Explanation:

Because this is a right triangle, you can use the Pythagorean theorem to solve it. In a right triangle, the sum of the squares of the two sides is equal to the square of the hypotenuse. Or in this example:

c² = 9² + 8²

So we can solve it:

c² = 9² + 8²

c² = 81 + 64

c² = 145

c = √145

c ≈ 12.04

Answer 2

a*2 + b* = c*2

(9)*2 + (8)*2

81+64= 145

145=c*2
12.04=c
