Answer:

x = 15

Explanation:

The 79° angle and the angle labeled (5x + 4)° are equal because they are vertically opposite. Therefore, we can equate them and solve the resulting equation:

5x + 4 = 79

⇒ 5x - 4 = 79 - 4 [Subtracting 4 from both sides]

⇒ 5x = 75

⇒ x =
(75)/(5) [Dividing both sides by 5]

x = 15
