Problem: Julian decided to take a boat ride on his brand new yacht. He takes it out for a spin and notices a cliff upcoming ahead. He wonders, if the angle of elevation to the top of the cliff is 52.53 degrees,  and the base of the cliff is 1236 feet away from the boat, how high is the cliff? (Remember round to the nearest foot)

Ivan was on top of a lighthouse observing Julian on his brand new yacht. He looked around and noticed at the bottom of the cliff where he was positioned, that there was a boiling crab. He found a parachute and thought, " I wonder how long will be the path I glide if the angle of depression is thirty degrees?"  Keep in mind he is already 300 feet above ground. 

The Solution: 

a)

B)
