The angle supplementary to x and 3x are equal.
Supplementary angles = 180
Solution
x + 3x = 180
4x = 180 Divide by 4
4x/4 = 180/4
x = 45
The angle supplementary to x is 3x
3x = 3*45
3x = 135
This angle is vertically opposite y. Vertically opposite angles are equal. So y = 135
Answer
x = 45
y = 135

Answer:
a = 2 
Step-by-step explanation:
Given
a = 
Multiply both sides by 9 ( the LCM of 3 and 9 ) to clear the fractions
3a = 7 ( divide both sides by 3 )
a =
= 2
