Answer:
2x is 64
x-6 is 26
We start by adding 6 to 90 (90 because all triangles have interior angle sums of 90, and the right angle makes up for the other 90), and then we divide by 3. (3 because thats how many times x is in the angles) then we have 32, so x = 32. From there, we can calculate the angle measures with the known variable. :)
