Hello, Myllhya. Whenever using unit rate, you set up a proportion: . Imagine the line in between x and y is the word 'per'. Finding how many feet in a given number of inches is the same as saying 'how many feet per inch', so this will be written as
because feet becomes dependent on inches. Or, vice versa, the problem asks for inches for a certain amount of feet, you apply the same concept. The number of inches depends on feet, so you proportion is
.
I hope this was helpful. : )

Answer:
15°
Step-by-step explanation:
Since P is on the median of ΔABC, it is equidistant from points B and C as well as from C and Q. Thus, points B, C, and Q all lie on a circle centered at P. (See the attached diagram.)
The base angles (B and C) of triangle ABC are (180° -30°)/2 = 75°. This means arc QC of the circle centered at P has measure 150°. The diameter of circle P that includes point Q is defined to intersect circle P at R.
Central angle RPC is the difference between arcs QR and QC, so is 180° -150° = 30°. Inscribed angle RQC has half that measure, so is 15°. Angle PQC has the same measure as angle RQC, so is 15°.
Angle PQC is 15°.
