Please help me it would mean a lot

Problem 10

Work Shown: 80-0 = 80

You subtract the values on the protractor where the two angle arms line up.

Problem 11

Work Shown: 45-0 = 45

Same idea as problem 10

Problem 12

Work Shown: 128-45 = 83

Same idea as the others. The arm TS isn't fully on 130 degrees, and it's a bit short of it. It looks to be about 128 degrees or so.

Problem 13

Explanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.
