Question

The supplement of 1/5 of 150

Answer 1

Answer:

Let the measure of its supplement be x°. Then,

other angle = x/5

x + x/5 = 180

=> 5x + x/5 = 180

=> 6x/5 = 180

=> x = 180 × 5/6

=> x = 150

∴ ,the measure of its supplement is 150°.

The other angle = 150°/5 = 30°

Answer 2

Let the supplement be x.

x+x/5=180
6x/5=180
x=180*5/6
x=150
