angle sum property x minus 10 and x minus 20 and x minus 30

Answer 1

Answer:80

Step-by-step explanation:x-10+x-20+x-30=180

3x-60=180

3x=240

x=80

Answer 2

Answer:

(x-10) +(x-20) + (x-30) =180

3x - 60 = 180

Divide by 3

x - 20 = 60

x = 80°

Angles are

x-10 = 80 - 10=70

x -20 = 80-20=60

x-30 = 80-30=50
