1) The question screenshot attached down below answer step-by-step.

5. Two people are standing 500 feet apart on opposite sides of a building. One determines that the angle of elevation to the top of the building from their position is 44°, and the other person determines it to be 47°. How tall is the building, to the nearest tenth? 6. An emergency signal is being emitted from a fixed position. One response team determines the signal to be at a bearing of 27°, while a second response team, 750m due east of the first team, determines the bearing to be 312°. Which team is closer to the emergency signal, and how far away is it, to the nearest tenth? Note: Bearing means the degrees clockwise from the north line. 7. Find the perimeter of AABC if A = 16°, B = 77° and a = 18.2, to the nearest tenth.
