Question

Please help me it would mean a lot

Answer 1

Problem 10

Answer: 80 degrees

Work Shown: 80-0 = 80

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

============================================

Problem 11

Answer: 45 degrees

Work Shown: 45-0 = 45

Same idea as problem 10

============================================

Problem 12

Answer: 83 degrees

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

Answer:  35 degrees

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.
