Question

If two angles forming a linear pair are 100º and a,find the value of a.

Answer 1

Step-by-step explanation:

two angles form a linear pair, then the sum of the degree measure of the angles is 180

0

.

Let x= measure of the smaller angle.

Then,

2x=measure of the other angle.

So,

x+2x=180

0

3x=180

0

x=60

0

The measures of the angles are 60

0

and 120

0

.
