.. Cos = Adjacent/Hypotenuse
.. cos(C) = 80/82 = 40/41 . . . . . . . . . . . seems to match the last selection
.65
13/20
Just simply divide and you get .65
The answer is 170. First you add base one and base two divide by twi the multiply that by the height. 18+22=40 40/2=20 20•8.5=170
\left[y \right] = \left[ -5\right][y]=[−5] totally answer
