Assuming the angle congruent to r is not a right angle, we can solve for a supplementary one.
70 + x + x=180
70 + 110=180
110 can be broken down into 55, which we can use for the other two sides.
I’m gonna assume angle R is 55°.
For angle S, same thing. 62 + x=180
The value for it is 118, half it and you get 59°.
Last but not least, angle u. Angle u is diff bc it’s complimentary. We know that one side equals 59°, so subtract 59 from 90, and the value of angle U is 31°.
Hope this helps! It’s been a while since I was in geometry so I hope I’m right too aha
