Question

Find the angles which are adjacent and form an angle of 150°. The greater angle is 30° less
then two times the smaller angle.​

Answer 1

Answer:

60,90

Step-by-step explanation:

Let the smaller angle be x

Then larger angle is 2x-30

x+2x-30=150

3x=180

x=60

smaller angle = x = 60

Larger angle = 2x-30 = 2×60-30 = 120-30 = 90

Answer 2

Answer:

50° and 70°

Step-by-step explanation:

2×smaller angle-30 = greater angle.

Taking value of smaller angle as 50° and that of greater angle as 70°, we get-

》(2×50)-30 = 70

》100-30 =70

Since LHS=RHS,

therefore value of smaller angle = 50°

And value of greater angle = 70°
