The peak of Mt. Fuji in Japan is approximately 12,400 feet high. A trigonometry student, several miles away, notes that the
angle between level ground and the peak is 20°. Estimate the distance from the student to the point on level ground directly
beneath the peak. (Round your answer to one decimal place.)

Stonehenge in Salisbury Plains, England, was constructed using solid stone blocks weighing over 99,000 pounds each. Lifting
a single stone required 550 people, who pulled the stone up a ramp inclined at an angle of 9°. Approximate the distance that
a stone was moved in order to raise it to a height of 30 feet. (Round your answer to the nearest whole number.)
