A 48-foot building casts a shadow 72 feet measured along the ground. What is the angle of the sun's position above the horizon? While flying a kite, Jimmy lets out 150 feet of string. If the string makes an angle of 38 degrees with the ground, (a) how high is the kite? (b) how far from Jimmy is his friend Jane, who is directly below the kite? (Ignore the sagging of the kite string; assume the ground is level.) You take a stroll one fine evening. First you go 4.0 kilometers to the east, followed by 8.0 kilometers northward. Tired from your 12.0-km walk, you call your roommate and ask him/her to fly your shared private helicopter from your home to your location, so you can skip the walk back. How far, and in which direction, does your friend need to go to find you? Give your direction as the angle measured clockwise from due north (called a bearing).

Question
Hello, I need help solving these three questions please. Thank you.
3.1 A 48-foot building casts a shadow 72 feet measured along the ground. What is the angle of the sun's
position above the horizon?
3.2 While flying a kite, Jimmy lets out 150 feet of string. If the string makes an angle of 38 degrees with
the ground, (a) how high is the kite? (b) how far from Jimmy is his friend Jane, who is directly below
the kite? (Ignore the sagging of the kite string; assume the ground is level.)
3.3 You take a stroll one fine evening. First you go 4.0 kilometers to the east, followed by 8.0 kilometers
northward. Tired from your 12.0-km walk, you call your roommate and ask him/her to fly your shared
private helicopter from your home to your location, so you can skip the walk back. How far, and in
which direction, does your friend need to go to find you? Give your direction as the angle measured
clockwise from due north (called a bearing).
