Question

Two angles are vertical angles. If one of the angles measures 35º and the other measures (4x+3)º, which algebraic equation can be used to solve for the value of x?

35 + 4x + 3 = 180

35 + 4x + 3 = 90

35 = 4x + 3

None of these are correct

4x + 3 = 90

Answer 1

35 = 4x+3

If they're vertical then they're worth the same or equal. So 4x+3 is equal to 35 and then you solve for x from there.
