An easy to remember equation for finding change in elevation as a decimal is rise over run.. as an example, let’s say the rise is 2 and the run is 6.. so you take 2 over 6 (or2/6) and divide .. so you’re answer is division my friend hope this helps

Problem 10

<h3>Answer: 80 degrees</h3>

Work Shown: 80-0 = 80

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

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

Problem 11

<h3>Answer: 45 degrees</h3>

Work Shown: 45-0 = 45

Same idea as problem 10

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

Problem 12

<h3>Answer: 83 degrees</h3>

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

<h3>Answer:  35 degrees</h3>

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.

In x^7•x^4, how many x’s are multiplied together? (There’s 7 in the first factor and 4 in the second.)

x^7•x^4 = x^__? This is your a-value.

Similarly, y^2•y^5 = y^__? How many y’s are there in total being multiplied? This is your b-value.
