Question

Both angle A & B are supplementary. If angle A is x and angle B is 3x, then what is x equal to AND what does angle B equal?

Answer 1

A= 45 degrees

And angle B= = 135 degrees

Explanation:

Supplementary means that the sum of both angles is equal to 180 degrees.

< A= x

< B= 3x

<a+<B= 180

x+3x= 180

4x= 180

x= 180/4

x= 45

Therefore angle A= 45 degrees

And angle B= 3x= 3*45= 135 degrees
