Question

what is the supplement of 27°? s = ?°

Explanation:

Step1: Recall supplement - angle formula

Supplementary angles add up to 180°. Let the given angle be $\alpha = 27^{\circ}$ and the supplement be $S$. Then $S+\alpha=180^{\circ}$.

Step2: Solve for the supplement

$S = 180^{\circ}-\alpha$. Substitute $\alpha = 27^{\circ}$ into the formula, so $S=180 - 27$.
$S = 153^{\circ}$

Answer:

$153$
