Answer:
The guys are wrong,I checked.
The factors of 32 are 1, 2, 4, 8, 16, and 32.
The factors of 20 are 1, 2, 4, 5, 10, and 20.
The common factors of 32 and 20 are 1, 2, and 4.
The greatest one is 4.
32 = 4 x 8
20 = 4 x 5
32 + 20 = (4 x 8) + (4 x 5)
32 + 20 = <em>4 (8 + 5)</em>
<span><span><span>(<span>−<span>320x</span></span>)</span><span>(7)</span></span>16</span><span>=<span>−<span>140
The answer is -140
Hope this helps!

C) 30, 60, 90 because right off the bat, the largest angle is 90 degrees and it is the ONLY answer in which it’s other 2 angles are summed up to equal to it. And the rest of the facts match up. 60 degrees is twice as 30
