9. A flagpole is situated at the top of a building 115 ft tall. From a point, P, in the same horizontal plane as the base, B, of the building the angles of elevation of the top, T, and bottom, F, of the flagpole are 63° and 58°, respectively. If the length of segment PF is x feet and the height of the flagpole is y feet, then which of the following equations solves for y? a. y = (x sin 5°) /sin 27⁰ b. y = (x sin 27º) /sin 5⁰ c. y sin 5° / (x sin 27º) d. y = sin 27° / (x sin 5°)
