Question

Please help or i am grounded

Answer 1

`x=140`

Explanation:

Do not get grounded.

An angle at a point is 360°.

So,
`x+120+70+30=360`

`x+220=360`

`x=140`

Answer 2

Remember this All the angles around a point when added gives a 360° !

Thus,

30+ X +70+120 = 360

=> X + 220 = 360

=> X = 140°
