3. Find the measure of the complement and the supplement of the angle.
m_G=129
complement is 33°, supplement is 789
complement is 789, supplement is 330
complement is 1689, supplement is 789
complement is 78°, supplement is 1689

complement is 78°, supplement is 168°

Step-by-step explanation:

Part 1) Find the measure of the complement

we know that

If two angles are complementary, then their sum is equal to 90 degrees

Let

C ----> the complement of the given angle

we have

so

substitute

Part 2) Find the measure of the supplement

we know that

If two angles are supplementary, then their sum is equal to 180 degrees

Let

S ----> the supplement of the given angle

we have

so

substitute

Step-by-step explanation:

Angle = 12⁰

Complement = 90 - 12 = 78⁰

Supplement = 180 - 12 = 168⁰
