Question

An angle is 300
less than two times its supplement. The measure of the
angle is

Answer 1

let x be the supplement

so according to the given question

2x-300+x=180

3x-300=180

3x=180+300=480

x=480/3=160

so supplement is 160

angle =180-160=20degree is the angle

Answer 2

Answer:

the angle is 30°

Step-by-step explanation:

supplementary angles means

sum of angles=180°

let the angles be x, 180-x

therefore,

x=300-2(180-x)

x=300-360+2x

x-2x= -60

-x= -60/2

thus,

x=30°

180-x= 150°
