Twinkly · Answer 1

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

Zachery Marshall · 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.
