Yup! We're all pretty good here.
If j is 52° and its a right angle, add 90° and 52°. Then subtract 180° from that answer. Because all triangles add up to 180°.
that would be 3 minutes and 45 seconds (:
I think the answer is 32% because if you turn 32% into a decimal (which would be 0.32) then multiply it by 25 you would get 8. Which then means if he stopped 8 times and went through 25 intersections then he stopped at 32% of the intersections. I hope this helps :)
