Answer 1

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

$(16x-12)=180$

$16x=180+12$

$16x=192$

$x=12$
