Idon’t understand how i would solve this?

1st: 116°

2nd: 64°

Step-by-step explanation:

Supplementary angles add up to 180 degrees. We can make the first supplementary angle be represented by: 2x - 12 and the second supp. angle be represented by x.

Make both of these expressions add up to 180.

(2x - 12) + (x) = 180

Combine like terms.

3x - 12 = 180

Add 12 to both sides.

3x = 192

Divide both sides by 3.

x = 64

Substitute 64 for x into the first supp. angle's expression.

2(64) - 12 = 116

The first supp. angle is 116 degrees and the second is 64 degrees.

ask goog great chance of finding the solution there

one set of data has more variation than the other. hope this !
