1 Jerry stands at a distance from the base of a 30 foot flag

1. Jerry stands at a distance from the base of a 30 foot flagpole and views its top at an angle of 42°. How far from the flag pole does jerry stand?

2. Find the angle of elevation of the sun when a 42 foot tree casts a shadow of 68 feet.

3. From the top of a tower 242 feet tall, a worker looks down and sees a car. The angle of depression to the car is 66°. How far is the car form the base of the building?

Solution

Solution: - Given h =30\', angle = 42

tan 42 = h/d

tan 42 = 30/d

d = 30/tan 42

d =30/0.9 = 33.32\'
