Answer:

x = 17

Explanation:

Linear Pair of Angles

A linear pair of angles are formed when two lines intersect each other at a single point.

The sum of angles of a linear pair is always equal to 180°.

The image shows a linear pair of angles 2x+9 and 8x+1. The sum is 180°, thus:

2x + 9 + 8x + 1 = 180

Simplifying:

10x+ 10 = 180

Subtracting 10:

10x = 170

Dividing by 10:

x = 170/10

x = 17
