Question

6. An angle
is twice its supplement. The measure of the angle is *
30°
120°​
90
60

Answer 1

let the angle be x°

according to the question,

x = 2( 180 - x)

x = 360 - 2x

x + 2x = 360

3x = 360

x = 360/3 = 120°

Answer 2

Answer:

120°

Step-by-step explanation:

let supplement angle be x

a/q the angle is 2x

so,

x+2x=180 (bcz sum of supplement angle is 180°)

3x=180

x=60°

so the angle will =2*60

=120°
