Alex wants to construct a line segment through r that makes the same angle with line segment qr as line segment pq. the figure below shows a step to construct a congruent angle at r:

Answer : To construct a line segment through R which would have the same angle with line segment QR . With the co-relation of segment QR which is same to segment PQ which means that angle Q and angle R are corresponding angles.

So, to construct the same angle with the segment keep the pointed compass end on R by measuring the same distance at the angle Q. Just draw the curve at R and there you are.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
