In Washington, D.C., Constitution Ave. meets Pennsylvania Ave. at a 25° angle. What is the measure of the complementary angle to the angle formed by these two avenues?

Answer 1

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°.
