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.
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
