Question

Tell whether the angles are adjacent or vertical. Then find the value of x

Answer 1

They are vertical.

107 = 3x - 4

Add 4 to both sides

111 = 3x

Divide both sides by 3

X = 37

Plug 37 into the equation

3 (37) -4 = 107

Answer 2

Vertical angles

x =37

Explanation:

Adjacent angles are next to each other and share one side

Vertical angles are across from each other and only share a vertex.

These angles are vertical angles. Vertical angles are equal

3x-4 = 107

Add 4 to each side

3x-4 +4 =107+4

3x = 111

Divide by 3

3x/3 = 111/3

x=37
