PLEAZE CORRECT IT OUT IM SORRY
Answer:
A= 45 degrees
And angle B= = 135 degrees
Step-by-step 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
6/5 x+
This is because you have one less coordinated plane
