these two angles are complementary. what is the measure of ∠x? ∠x = ?°

Explanation:

Step1: Recall complementary - angle definition

Complementary angles add up to 90°.

Step2: Set up the equation

Let the measure of ∠x be (x). We know that (x + 19^{\circ}=90^{\circ}).

Step3: Solve for (x)

(x=90^{\circ}- 19^{\circ}).
