X=18 degrees
You are working with a right angle triangle
A triangles total degrees should add up to 180
any right angle is 90 degrees
so to find your x value of degrees you take your right angle 90 degrees add it to your value of 72 degrees. This gives you 162 degrees so to find x you subtract 162 degrees from 180 giving you 18 degrees your x value :)
I hope this helped :)

Well they give you one angle which is 72, we all know that a right angle equals 90 degrees. this triangle has to have a sum of 180. so add 90+72= 162 then subtract 180-162=18. that's gonna be your answer, hope it helped :)
