Question

For what value of X, L is parallel to M . Refer the above figure​

Answer 1

so given one angle 120 and 50 so find x so

now drop a line that cuts the x-20 half so it passes through that angle

so now it will become (x-20)/2

so it is equal to 120 degrees angle beacuse they are vertically opposite angles

so by simplification of

(x-20)/2=120

we get

x=220 degrees
