Question

Find the value of X using your method​

Answer 1

`x = 30`

Explanation:

In the diagram above, MN is a straight line which equals 180.

RL is vertically opposite to KS

(Vertically opposite angles are equal ⟹RL = KS).

So, MN becomes:

`90 + 2x + 30 = 180`

Collect like terms

`90 + 30 + 2x = 180→120 + 2x = 180→2x = 180 - 120→2x = 60`

Divide 2x = 60 by 2

`x = (60)/(2)`

Therefore:
`x = 30`
