Question

Find the measure of the angle which is half of its supplementary angle?

​

Answer 1

Answer:

60°

Step-by-step explanation:

⇒x=180−x2

Multiply 2 on both the sides, we get,

⇒2x=180−x

Separating variables and constants we get,

⇒2x+x=180

⇒3x=180

We need the value of x

, so divide both sides by 3.

⇒x=180/3

(Using simple division.)

⇒x=60

An angel which is half of its supplement is of 60

Answer 2

Let the angle be y and its supplement be 180 −y

ACQ,

⇒y= 180° −y/2

⇒2y=180° −y

⇒2y+y=180°

⇒3y=180°

⇒y= 180°/3

⇒y=60°
