Solve word problems by modeling real-world (and not-so-real) situations as right triangles and using trigonometry.


Galileo wanted to release a wooden ball and an iron ball from a height of 150 meters and measure the duration of their fall.
He found a plane with an incline of 15, degree that he could climb until he gets to an altitude of 150, space, m.
How far should Galileo walk up the inclined plane?
Round your final answer to the nearest hundredth.
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, p, i or 2, slash, 3, space, p, i
