Answer:

(2x+7)° + (5x+4)° + 69° = 360°

=> 2x + 7 + 5x + 4 + 69 = 360

=> 7x + 80 = 360

=> 7x = 360 – 80

=> x = 280/7

=> x = 40

Answer:

x=40

Step-by-step explanation:

(2x+7)*+(5x+4)*+69*=360*   (360* because its a circle)

7x+80=360       (combine like terms)

- 80     -80      (minus 80 both sides)

7x=280      (divide 7 both sides)

x=40
