Question

The two angles shown form a linear pair. What is the value of 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.

Question 5 options:

9.5


12


180


90

Answer 1

The answer is 12.

Explanation:

A straight line is 180. Adjacent angles in that line equal 180. Add 10x-20 and 6x+8, which equals 16x-12. Make 16x-12 equal to 180 and add 12. 16x=192, divide both sides by 16 and x=12

Answer 2

Answer: 12

Step By Step: 10x - 20 + 6x + 8 = 180
16x - 12 = 180
16x = 192
x = 12
