- Vertical Angles: angles that are cross from each other and congruent
Step-by-step explanation:
Step 1: Identify
We notice from the picture that the 2 angles are vertical.
Step 2: Set up equation
x + 12 = 5x - 48
Step 3: Solve for x
- Subtract x on both sides: 12 = 4x - 48
- Add 48 to both sides: 60 = 4x
- Divide 4 on both sides: 15 = x
- Rewrite: x = 15
