Sagot :

Answer: 12

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

Answer:

The answer is 12.

Step-by-step 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
