Which angle is complementary to ∠4?

To determine which angle is complementary to ∠4, we need to know that two angles are complementary if their measures add up to 90 degrees.

If you have the measure of ∠4, you can find its complementary angle by subtracting that measure from 90 degrees.

For example, if ∠4 measures 30 degrees, then the complementary angle would be 90 – 30 = 60 degrees. You would then check which of ∠1, ∠2, ∠3, or ∠5 equals 60 degrees.

Please provide the measures of the angles if they’re not given, so we can find the complementary angle together!
