Fpr purposes of making on-campus housing assignments, a college classifies its students as Priority A niors), Priority B (Juniors) and Priority C (freshmen and sophomores). Of the students who choose to live on campus, 10% are seniors, 20% are juniors, and the rest are underclassmen. The most desirable dormis the newly constructed Gold dorm, and 60% of the seniors elect to live there 15% of the Juniors alo live there along with only 5% of the freshmen and sophomores. What is the probability that a randomly selected resident of the Gold dorm is a senior?

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
