When Donelle stands at point R, he is 1000 feet from point S at the base of a cliff. When he looks up at an angle of 20°, he sees a friend at the top of the mountain cliff at point T. Which measurement is the closest to the height of the mountain cliff in feet?

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

10 down (bang1)

5 up

5down (2)

2.5 up

2.5 down (3)

1.25 up

1.25 down (4)

now add them up : )

hoped i lol

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

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.
