Question 1062052
Do you know how much supplementary angles measure when you add up their angles?
Look that up, then subtract 55 to find your angle.
:
Easy way to remember:
Complementary
C stands for "corner" (a right angle, like the one in the picture below. A right angle measures 90 degrees, and that's how much two complementary angles add up to.
Supplementary
S stands for "straight", the angles of two supplementary angles for a straight line which is 180 degrees.
