Find the supplement of $\frac{3}{4}of160°$

Finding the supplement angle

Let the supplemet angle be $x$

Given angle is $\frac{3}{4}of160°$$=\frac{3}{4}\times 160°$

$$\begin{gathered} =3\times 40° \\ =120° \end{gathered}$$

The sum of two supplement angles is $180°$

Thus,

$$\begin{gathered} x+120°=180° \\ x=180°-120° \\ x=60° \end{gathered}$$

Hence, the supplement of $\frac{3}{4}of160°$ is $60°$
