So been at this for about an hour, got the first one, no clue on the second, can anyone offer assistance?

K(-2, 7), L(8, 7), M(14, -1), N(4, -1) are the vertices of a quadrilateral.

Calculate the angle that the lines LN and KM make with the x-axis.

For LN I worked out the gradient/slope of the line and used the inverse of tan to come to the solution 63.4 which seems to be correct. However with KM employing the same method doesn't produce the correct result.

Thanks for any help.
