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
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
A 150-foot-long ramp connects a ground-level parking lot with the entrance of a building. if the entrance is 8 feet above the ground, what angle does the ramp make with the ground. draw the picture
