Question

In the diagram below, find the value of x to the nearest hundredth

Answer 1

x = √324 = 18

Explanation:

x shows up only in the second problem, so I'll focus on that problem.

This is a right triangle because one of the three angles is 90 degrees.

Thus, the Pythagorean Theorem applies: x^2 + 24^2 = 30^2, or

x^2 = 900 - 576 = 324

Then x = √324 = 18
