# Thread: Finding the height with trig

1. ## Finding the height with trig

Hi, can someone help me how to do this problem. Thanks a lot.

$\displaystyle \sin \theta = \frac{{opposite}}{{hypotenuse}}$
$\displaystyle \begin{array}{l} \sin \theta = \frac{{height}}{{road}} \Rightarrow height = road \times \sin \theta \\ \\ height = 20ft. \times \sin 2^\circ = 0.7ft. \\ \end{array}$
