Answer 2

Answer:

To find : value of x

Given : measure of other angle =  65°

let ∠ $1$ be x and ∠ 2 be  65°

here we can see that both the angles ∠ $1$  and ∠ 2 are linear pair of angles.

• The two angles of a linear pair , like ∠1  and  ∠2 in the figure are always supplementary.

• Supplementary angles are two angles whose measures add up to 180

Therefore ,  ∠ $1$ +  ∠ 2 = 180°

                   x +  65° = 180°

                   x = 180° - 65°

                   x = 115°

Hence measure of angle x is  115° .
