The lengths of two sides of a right triangle are given. Find the length of the third side. Round to the nearest tenth if necessa

marta [7]

The answer is <span>D. 31.8 in.</span>

Since this is the right triangle, we can use the Pythagorean theorem:
c² = a² + b²
(c - hypotenuse, a and b - sides)

a = 28 in
b = 15 in

c² = 28² + 15²
c² = 784 + 225
c² = 1009
c = √1009
c = 31.8 in
