Question

Please help me Note:Angels not necessarily drawn on scale

Answer 1

Explanation:

We can clearly see that:-

EAD is a straight line.

So, we can say that the total value of angle they will make is 180°.

Now, if I form the equation, it will be:-

`100 + x + 20 = 180`

`120 + x = 180`

`x = 180 - 120`

`\boxed{ \boxed{x = 60 ^ \circ}}`

is the answer

Hope it helps :D
