Question

1. When you look down from the top of a building at an angle of 63degrees, you will see a man reading a newspaper. If the building is 50m high, how far is the man from the building?

2. A plane takes off at an angle of 15deg20'. How high will it have risen after it has flown a slant distance of
20 000 m?

Answer 1

a, Tan 27=50/d solve for d

b. sinAngle=h/20,000
solve for h.

Answer 2

50/x = tan 63

x/20000 = sin 15.33
