Question

Question46 in.2The figure above shows a right triangle with dimensions in inches. If O=30°, what is the length of to the nearest inch?

Answer 1

For angle 30 degree, perpendicular side is 46 in and base side is x.

Determine the measure of side x by using trigonometric ratio.

$\begin{gathered} \tan 30=\frac{46}{x} \\ x=\frac{46}{\tan 30} \\ =79.67 \\ \approx80 \end{gathered}$

So value of x is 80 in.
