Question

for the following right triangle, find the side length x. round your answer to the nearest hundredth.​

Answer 1

x = 12

Explanation:

We can use the Pythagorean theorem to solve

a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse

9^2 +x^2 = 15^2

81 +x^2 = 225

Subtract 81 from each side

81-81 +x^2 = 225-81

x^2 = 144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x = 12
