Question

For the following right triangle, find the side length x. Round your answer to the nearest hundredth. Side 15 bottom x 25 upper

Answer 1

x = 20

Explanation:

To do this question, you can use the pythagorean theorem. c is your hypotenuse, a is the unknown side length and b is the known side length.

a^2+b^2=c^2

x^2+15^2=25^2

x^2=225=625

x^2=400

(x^2)^(1/2)=400^(1/2)

x = 20
