divide both sides by -21
flip sign
16<u><</u>y

they seem to have the same solution

Snezhnost [94]

The answer is D. 42

A triangle equals 180 in total so what you would do it subtract 122 from 180 because 180 is also the angle of a straight line. You would get 58 then you add 58 and 80 to get 138. Subtract 138 from 180 and you get your answer of 42
