Question

The measure of an angle is 108.4°. What is the measure of its supplementary angle?

Answer 1

Answer:

x =71.6

Step-by-step explanation:

Supplementary angles add to 180 degrees

Let the unknown angle be x

x+108.4 = 180

Subtract 108.4 from each side

x+108.4-108.4 = 180-108.4

x =71.6

Answer 2

Supplementary angles are two angles that add up to 180 degrees. We can subtract to find the other angle.

180 - 108.4 = 71.6 degrees

The second angle is 71.6 degrees.
