Question 1101001: a and b are complementary angles.
if a=b, find the value of a.

You can put this solution on YOUR website!
if angle a and b are complementary, then their sum is 90.

you get a + b = 90

since a = b, you can replace b with a to get a + a = 90

combine like terms to get 2a = 90.

solve for a to get a = 45 degrees.
