Question

Can someone answer this please with an explanation.

Answer 1

92°

Explanation:

180 degrees on a straight line.

2x - 4 = 180

2x = 184

X = 92°

Answer 2

x=92

Explanation:

those to angles are supplementary meaning that they add up to equal 180

so you set up the equation 180=x+x-4

180=2x-4

step 1 add 4 to each side

184=2x

step 2 divide each side by 2

x=92

so the angles equal 92 and 88
