Question

In this figure, ∠1 and ∠2 are located on a line.

Answer 1

Answer:

x = 11.25

Step-by-step explanation:

Two adjacent angles on a line are supplementary.

That means their measures add to 180°.

Add the measures of angle 1 and angle 2 and set the sum equal to 180.

Then solve for x.

m<1 + m<2 = 180°

x + 15x = 180

16x = 180

x = 11.25
