PLZ HELP ME THIS IS 7th grade math

The answer is: x = 18.

Step-by-step explanation:

1) That is a right angle, so it equals 90 degrees. You can add together the 'x'es that you see in the photo, and x + x +3x = 5x.

2) Set that equal to 90, so: 5x = 90.

3) Divide by 5 on both sides, to get x = 18.
