Me with question. first answer correct that explains = brainlist

Angles ∠1 and ∠3 are supplementary angles meaning that their measures must add to 180°.

Let's call the angles a and b. Angle a is ∠1 and angle b is ∠3. Now let's write what we know.

a = b - 10
a + b = 180

The first equation is solved for a, so we can plug b - 10 in for a in the secnd equation.

(b-10) + b = 180

2b - 10 = 180

2b = 190

b = 95

If b = 95, then we know that a = 95 - 10 = 85.

We know ∠1 and ∠2 are equal because they are alternate inferior angles. The same applies to ∠3 and ∠4.

The answer is D.
