Answer:
156 degrees
Explanation:
Bisects meand to cut into two equal halves.
That means 4x-2=3x+18.
Subtracting 3x on both sides gives x-2=18
Adding 2 on both sides gives x=20
If x=20, then 4x-2 equals 4(20)-2=78.
The other half is also 78 since the two angles were comgruent.
The whole angle is 78+78=156.
