What fraction of Juan's shifts had total sales of $225 or more?

step-by-step explanation:

1. perpendicular

2. parallel

3. perpendicular

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

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.
