Question

What is the value of x? Enter your answer in the box. x = Horizontal line divided by a diagonal line. The angle formed on the left by the two lines is labeled 10 x minus 20 degrees. The angle formed on the right by the two lines is labeled 6 x plus 8 degrees.

Answer 1

Here the two angles are supplementary, which means sum of these angles equal to 180 degrees.
So equation is:
10x-20+6x+8=180
Add like terms
16x-12=180
16x=192
x=12

Answer: x=12
