Question

Two angles are supplementary. The larger angle 120

greater than the twice the measure of

the smaller angle. Find the measure of each ​

Answer 1

Step-by-step explanation:

let the number be x then solve the equation

Answer 2

Answer:

Let the smaller angle be r°

Let the larger angle be (2r + 120)°

We know that sum of two angles equal to 180° is know as supplementary.

A/q

⟶r+2r+120°=180°

⟶3r+120°=180°

⟶3r=180°−120°

⟶3r=60°

⟶r=

3

60°

⟶r=20°

Thus;

the smaller angle = 20

the larger angle = 2r+120=2*20+120. = 140
