Question

Two angles form a linear pair. One angle measures

2
x
and the other angle measures
10
x
. Find the measure of the smaller angle.

Answer 1

30 degrees

Explanation:

a linear pair adds up to 180 degrees. therefore, you can compose the equation 2x+10x=180

12x=180

x=15

the smaller angle is 2x, so 2 times 15 is 30
