Carlos leaned a 30 foot long ladder against his house to climb on the roof. He placed the base of the ladder 18 feet away from the wall. How tall is the lowest point of the roof?

answer: apothems is your answer

step-by-step explanation: hope u get it right

answer: 486in^2

step-by-step explanation:

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.
