Question

the angel of a triangle are x,x+10 and x+20 .Find the angles?​

Answer 1

Step-by-step explanation:

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

3x + 30 = 180

x = 150 ÷ 3 = 50

1st angle = 50°

2nd angle = 60°

3rd angie = 70°

Answer 2

Answer:

70

Step-by-step explanation:

X+X+10+ X+20 = 180

3X + 30 = 180

3X = 150

X = 50

X+10 = 60

X + 20 = 70
