While standing atop a building 50.7 m tall, you spot a friend standing on a street corner. Using a protractor and a dangling plumb bob, you find that the angle between the horizontal and the direction to the spot on the sidewalk where your friend is standing is 23.5°. Your eyes are located 1.98 m above the top of the building. How far away from the foot of the building is your friend?
