The value of the angle is 85° and 95°.

The image shows a pair of parallel lines with arrows pointing in opposite directions. The two angles marked 5x+15 and 7x-3 are supplementary angles, meaning that they add up to 180 degrees.

5x+15 + 7x-3 = 180

12x+12 = 180

12x = 168

x = 14

The angle value is

5x+15

= 5 (14) + 15

= 70 + 15

= 85°

7x-3

= 7 (14) - 3

= 98 - 3

= 95°
