Ruth is flying a kite. Her hand is 3 feet above ground and is holding the end of a 300 ft. kite string, which makes an angle of 57 degrees with the horizontal. How high is the kite above the ground

ignoring the 'sag' in the line, ...

sin 57 = (height+3)/300
height + 3 = 300sin57
height = .....

oops make that

height = (300sin57) + 3

• Precalculus`! -

so the answer is about 248.6 ft
what i was doing wrong was I wasn't thinking about adding the three which had my answer off

so the real answer is about 254.6
