Chapter 8.4, Problem 25PPS

To determine

The value of $\sin 30°$

Answer to Problem 25PPS

  $\begin{array}{l}\sin 30°=\frac{1}{2}\\ \sin 30°=0.50\end{array}$

Explanation of Solution

Given:

  $\sin 30°$

Calculation:

The $30°-60°-90°$ triangle can be drawn as:

The value of $\sin 30°$ will be:

  $\begin{array}{l}\sin 30°=\frac{\text{Opp}\text{.}}{\text{Hyp}\text{.}}\\ \sin 30°=\frac{x}{2x}\\ \sin 30°=\frac{1}{2}\\ \sin 30°=0.50\end{array}$
