  • 0:00 - 0:03
    The answer is 60.9 degrees.
  • 0:03 - 0:07
    We get that by saying, well, the opposite and the adjacent side,
  • 0:07 - 0:16
    so we know that the tan β is equal to opposite over adjacent--18/10.
  • 0:16 - 0:18
    But we want to know what β is itself.
  • 0:18 - 0:23
    We actually have to look at the arctangent of 18/10.
  • 0:23 -
    If we look at the arctangent of 18/10, we get 60.9 degrees.
