Answer:

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.

A+b=180
a=19*b

19b+b=180
20b=180
b=180:20
b=9°
a=19*9=171°

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
