Question

In the adjoining figure, the value of x is:
3x
2x0
7.xº​

Answer 1

Answer:

Step-by-step explanation:

1] 3x + 20° + 4x - 36° = 180° (linear pair)

  7x - 16 ° = 180°

  7x = 180 + 16

  7x = 196

  x = 196 ÷ 7

  therefore x = 28

2] 5x + 11x + 2x = 180°

⇒ 18x = 180°

⇒ x = 10°

3] 3x+7x+2x=180  

∘ 12x= 180/12  =15

∴ Value of {x = 15}
