What is complementary and supplementary angle?
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
What is a supplementary angle example?
Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°. Similarly, complementary angles add up to 90 degrees.
How do you find complement and supplement angles?
To determine the supplement, subtract the given angle from 180. 180 – 43 = 137° The supplement of 43° is 137°. To determine the complement, subtract the given angle from 90. 90 – 43 = 47° The complement of 43° is 47°.
What is the measure of ∠ DBC?
Therefore, the measure of ∠DBC is 72°.
What is the complement of 90 A?

What is the supplement angle of 93?
93° and 87° are supplementary angles.
What is the complement of 64?
26^∘
The measure of complementary angle of 64^∘ is 26^∘ .
What is the supplement of 156 degrees?
The supplement of 156° is the angle that when added to 156° forms a straight angle (180° ).
