Question

If 40% of an angle is the supple ment of 150°, find the angle​

Answer 1

Answer:

It's 12°

Step-by-step explanation:

The supplementary angle of 150° is 30° as the sum of both gives 180°.

Now 40% of 30° is simply 12°.

Answer 2

Step-by-step explanation:

let 1st angle = x

40% of x = 40/100x

a.t.q sum of supplementary angles = 180°

2nd supplementary angle = 150°

value of x = 40/100x + 150° = 180°

40/100x = 180° - 150°

x = 30° × 100/40

x = 30 × 10/4

=300/4

x = 75°

therefore angle = 75°
