A and B are vertical angles. If m A = (4x + 14) and m B = (5x – 5)º,
then find the measure of A

Vertical angles are equal/congruent

4x+14=5x-5

X=19

4(19)+14= 90

Angle A= 90

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
