Q:
# 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 angleb.

Accepted Solution

A:

Answer:Angle A= 135 degreesAngle B= 45 degreesStep-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
=180x=45Therefore, angle B is 45 degrees, and angle A is three times as large as angle B, or 135 degrees.
