If the measure of an angle is 3a, what is the measure of its complement?

Complementary angles are two angles that add up to 90°.

For this, we need to know what the value of a is. If you have this value, plug it into this equation:

90 - 3a = measure of complementary angle

For example, if a = 20:

90 - 3(20) = x

90 - 60 = x

30° = measure of complementary angle

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
