of its supplement. Find its measure.​

Answer 1

Answer:

Angle = 135

Step-by-step explanation:

Let the small angle be= x

:. Large which is 3 times its supplement = 3*x =3x

Sum of two supplementary angles = 180 degrees

:. x+3x=180 degrees

=> 4x = 180

:. x = 180/4

:. x = 45(small angle)

=> 3x = 3*45 = 135 degree (large angle)

Ans] The angle that is 3 times its supplement angle is 135 degrees.
