which angle is complementary to ∠1?
which angle is complementary to ∠1?
Answer
Explanation:
Step1: Recall complementary angles definition
Two angles are complementary if their sum is 90 degrees.
Step2: Observe the figure
We see that $\angle1+\angle2 = 90^{\circ}$ (since $\angle3$ is a right - angle and the angles around the intersection are related such that the non - overlapping angles $\angle1$ and $\angle2$ make up a right - angle).
Answer:
$\angle2$
