Question is 100 points the question is in the pic

For number 5: 180 -139 = x

For number 6: x = 41

For number 7: x + 18 = 90 (not 100% sure)

For number 8: x = 72

For number 9: you could write an equation about an acute angle and divide it into 2 parts the have one side 3 + 8 and have the other x. Then you could go from there. I’m sorry if you can’t figure out number 9. I tried to think of something.
