if angle A and angle B are vertical angles. if angle A = (8x – 4)º and angle B = (7x + 3)º,

Angle B is 52 degrees
If they are vertical angles then A and B will equal the same angle
To solve make this equation
8x-4=7x+3
Add the 4 to the 3 on the other side of the equation
8x=7x+7
Next subtract 7x from 8x
1x=7
Now we know what x is, so the last step is to multiply and add.
7•7=49
49+3=52
