Answer:

x=12

Step-by-step explanation:

we know that

A linear pair is two angles that are adjacent and form a line. The angle measure of a line is 180 degrees

In this problem we have that

(10x-20)^o+(6x+8)^o=180^o --- by supplementary angles (form a linear pair)

solve for x

(16x-12)=180

16x=180+12

16x=192

x=12
