If angle a and angle b are supplementary angles and angle a is nineteen times as large as angle b, find the measures of angle a and angle b.

Angle A= 135 degrees

Angle B= 45 degrees

Step-by-step explanation:

If x equals the measure of angle ​B, then  3x equals the measure of angle A.

Since these angles are​ supplementary, the sum of the angles is  180 degrees.

Solve for x.

x+3x  =180

4x =180

x=45

​Therefore, angle B is 45 degrees​, and angle A is three times as large as angle ​B, or 135 degrees.

i think it is c, not positive though
