Answer 1

when lines intersect like that then the 'opposite angles' are equal (think of a pair of scissors - the blades open by the same angle that the handles open!)

So the 2 angles marked in the diagram are equal

so 6(x-2) = (3x+30)

So now you can work out a value for x

Then use that to find the angle
