Question

an angle is 1/5 of its supplement . what is the degree measure of the angle

Answer 1

Heya ☺

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

Hence , the measure of its supplement is 150°.

The other angle = 150°/5 = 30°




Thanks

Answer 2

Answer:

Step-by-step explanation:

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

Hence , the measure of its supplement is 150°.

The other angle = 150°/5 = 30°
