By definition, the complementary angles are those that have a sum of 90° (Right angle).
The problem indicates that Constitution Avenue meets Pennsylvania Avenue at a 25° angle. Then, the complementary angle is:
Complementary angle=90°-25°
Complementary angle=65°
What is the measure of the complementary angle to the angle formed by these two avenues?
The answer is: The measure of the complementary angle to the angle formed by these two avenues is 65°.
