A person flying a kite holds the string 4 feet above ground level. The string of the kite is taut and makes an angle of 60° with the horizontal (see the figure). Approximate the height of the kite above level ground if 500 feet of string is payed out. (Round your answer to one decimal place.)

Height= 4ft + 500cos60, multiply cos60 which is 1/2 by 500 and add 4 feet. Use cos because it is adj/hyp. Which is 4'+500sin(60)
Almost. Use sin60°, since we want the height, not the distance along the ground.
The ground is the "adjacent" side here.

h-4/700 = sin60°
