Question

find the value of x please help​

Answer 1

= 120 - 180 = 50. (linear pair )

= 50 + x + 2x + (x +20) = 360. ( angle sum )

= 50 + 3x + x + 20 = 360

= 4x + 70 = 360

= 4x = 360 - 70

= 4x = 290

= x = 290 ÷ 4

= x = 72

I hope it helps you ..... ❤

Answer 2

First : 120°+120°+x+x = 360°

=> 2x = 120°

=> x = 60°

Now, According to the question :

x° + 2x° + (x+20°) + 60° = 360°

=> 4x = 280°

=> x = 70°

Now, Angles are : 70° , 70×2 = 140° , (x+20)°=90°

and 60°
