Question

pls tell me the answer​

Answer 1

Answer:

ATQ,

x + (x+10) + (x+20) = 180°

= 3x + 30 = 180°

3x = 180-30

= 3x = 150

x = 150/3

x => 50°

Since, x is equal to 50°, The angles are-

<1 = 50°

<2 = (x+10) = (50+10) = 60°

<3 = (x+20) = (50+20) = 70°

Hence, The sum should be 180°

= 50° + 60° + 70°

= 180°

Therefore,Our equation is correct!
