Answer: X + 12
Reason/Explanation:
It's asking us to write the words as an algebraic expression. "The width plus twelve." For starters, we don't know what the width is, so we use a variable, X. Now we add 12. So we use X + 12. The width is X, plus twelve.

Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle (
).
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
