Multiply both sides of the simplified equation you wrote in problem 2 (3 1/2x=280) by a fraction to get x alone on the left side of the equation. Simplify

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

for future students the answer is b
