Answer:

x=15

Step-by-step explanation:

The angle 3x+18 and 8x-3 are supplementary angles, which means they equal 180.

Set the angles equal to 180:
3x+18+8x-3=180

Simplify:

11x+15=180

Subtract 15 from each side

11x=165

Divide by 11 on each side

x=15

Answer:

[tex](3x + 18) + (8x - 3) = 180 \\ 11x + 15 = 180 \\ 11x = 165 \\ x = \frac{165}{11} \\ x = 15 \\ [/tex]
