Rzqust [24]

Answer:

- 2x - Зу = - 9

 9x +9y = 0

-6x - 9y = -27

 9x +9y = 0

3x =-27

=> x = -9

=> y = -x = 9

Find the measure , I need help
ehidna [41]

Answer:

166°

Step-by-step explanation:

Since ∠A = ∠B,

the equation below helps to find the value of x and angle A:

  • 7x + 40° = 3x + 112°
  • 7x - 3x = 112° - 40°
  • 4x = 72°
  • x = 72°/4
  • x = 18°
  • ∠A = 7*18° + 40° = 166°
