Question

In a pair of vertical angles one

angle measures 46° and the
other is (2x+7)º. Determine the
value of x.

Answer 1

19.5

Explanation:

We are given the pair of angles are vertical angles, meaning they are congruent or equal. We can use this to set up an equation to solve for x...

46=2x+7

Subtract 7 from both sides

39=2x

Divide both sides by 2

x=19.5
