LA and B are vertical angles. If m_A = (5x + 5) and m_B = (4x + 29), then find the measure of_A.​
OverLord2011 [107]

Answer:

If A and B are vertical angles, then they are congruent, so their measures are equal.

This means

(5x + 5)º = (4x + 29)º

5x + 5 = 4x + 29

x = 24

Then angle A has measure (5*24 + 5)º = 125º.
