Question

complementary and supplementary angles (no visual)
∠x and ∠y are supplementary angles. ∠y measures 88°. what is the measure of ∠x?

Explanation:

Step1: Recall supplementary - angle property

Supplementary angles add up to 180°. So, $\angle x+\angle y = 180^{\circ}$.

Step2: Substitute the value of $\angle y$

Given $\angle y = 88^{\circ}$, then $\angle x=180^{\circ}-\angle y$.

Step3: Calculate $\angle x$

$\angle x = 180 - 88=92^{\circ}$.

Answer:

92
