Answer:
Step-by-step explanation:
i believe the answer is a
X=-2y+1
x=y-5
so, both are equal
-2y+1=y-5
-3y=-6
so y=2
and x= -3
I believe C/12=pi which means the answer would be B.
Answer:
x = 18, y = 45
Step-by-step explanation:
4x - 7 + a = 180 (linear pair)
But, a = 6x + 7 (alternate interior angles)
=> 4x - 7 + 6x + 7 = 180
=> 10x = 180
=> x = 18
Now, 3y - 20 = 6x + 7 (vertically opposite angles)
=> 3y - 20 = 6(18) + 7
=> 3y = 108 + 7 + 20
=> 3y = 135
=> y = 45
