Question 1 1 V B 0/10 pts '0 5 8 99 G) Details A survey team is trying to estimate the height of a mountain above a level plain. From one point on the plain, they observe that the angle of elevation to the top of the mountain is 27. From a point 2000 feet closer to the mountain along the plain, they find that the angle of elevation is 32 . How high (in feet) is the mountain? Round to the nearest foot.

Question 12 v B 0/10 pts '0 5 8 99 G) Details The angle of depression of an object refers to the angle whose initial side is a horizonal line above the object and whose terminal side is the line-of-sight to the object below the horizontal. From a fire tower 200 feet above level ground in the Sasquatch National Forest, a ranger spots a fire off in the distance. The angle of depression to the fire is 2.4. How far away from the base of the tower is the fire? Round to the nearest foot.
