Answer:

x = 29

(x + 3)° = 32°

(x - 1)° = 28°

(x + 1)° = 30°

Step-by-step explanation:

  • (x + 3)° + (x - 1)° + (x + 1)° = 90°

  • -> (x + x + x +3 -1 + 1)° = 90°

  • -> (3x + 3)° = 90°

  • -> 3x + 3= 90

  • -> 3x = 90 - 3

  • -> 3x = 87

  • -> x = 87/3

  • -> x = 29

  • -> (x + 3)° = (29 + 3)° = 32°

  • -> (x - 1)° = (29 - 1)° = 28°

  • -> (x + 1)° = (29 + 1)° = 30°
