Question

Which trig function could be used to find the measure of angle c if ab and ac are given which equation would used to find the height of the flagpole with the hypotenuse is 5 m and the angle as 50 degress?

Answer 1

Let x represent the height of the flagpole.

sin 50 = opposite/hypotenuse
          = x/5
5 sin 50 = x
  3.83 = x

Answer: 3.83 m
