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.
Answer:
Step-by-step explanation:
Factors of 9: 1, 3 and 9.
Negative Factors of 9: -1, -3 and -9.
Prime Factors of 9: 3.
Prime Factorization of 9: 3 × 3 = 32
Sum of Factors of 9: 13.
Answer:
x = 13.5
Step-by-step explanation:
2/11 = 3/(3 + x)
6 + 2x = 33
2x = 27
x = 13.5
For the first one, its 86 square in, and the second one is 45 square cm.
Divide 914/420, move the decimal over to the right two places and you'll get approximately 217.5%
