The river falls vertically compared to how far it flows horizontally. Find the slope of the river shown to the right. (Hint: The slope of a river is positive.)
46 ft
252 ft

23 / 126

Step-by-step explanation:

46/252 = 23/126

c. 1,233 miles

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.
