Answer:

  • Vertical angles
  • x = 14
  • 84°

Step-by-step explanation:

The indicated angles are vertical angles since formed by two intersecting lines.

We know the vertical angles are congruent. Use this property to find the value of x and the angle measure

  • 6x = 3x + 42
  • 6x - 3x = 42
  • 3x = 42
  • x = 42/3
  • x = 14

The angle measure

  • 6*14 = 84

Opposite angles are equal

  • 6x=3x+42
  • 6x-3x=42
  • 3x=42
  • x=42/3
  • x=14
