Find the value of x. Write your answer in the simplest form.

Answer 1

9
`√(2)`/2

Explanation:

Since this is a right triangle designated by the square box in the right side, we know 2 of the angles. 45 and 90. Add these 2 angles and subract them from 180 which turns out to be 45.

We can use the law of sines to solve.

sin90/9 = sin45/x

x = 9sin45 = 6.36 = 9
`√(2)`/2
