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
Answer:
x = 2.
Step-by-step explanation:
Let the number be x.
Write it as an equation :-
6x - 3 = -1x + 11
6x + 1x = 11 + 3
7x = 14
x = 2.
