2. Building X is 100ft tall. Building Y is 200ft away from building X, where the distance is measured from the bottoms of the two buildings. Building Y is shorter than building X. The angle of depression from the top of building X to the top of building Y is 10° (a) Draw a diagram to the right showing the two buildings. Label known lengths and angles. (b) Find the height of building Y. (c) Find the angle of depression from the top of building Y to the bottom of building X. 00303000 13. A plane took off from a runway along a 5° angle of elevation. After 120 miles along that angle, it reached cruising altitude, and leveled off. (a) How far east did the plane travel before reaching the cruising altitude? Sins - 120 10.4 = x (b) What was the cruising altitude? sins = 10.4 Cuis 120 = 108.8 14. A rectangle has sides of length 6 and 10. Find the measure of the smaller angle formed loro its two diagonals cross.
