I have a trapeziod @ the top left is L, top right is M, bottom right is N and the bottom left is K. With 12x + 17 is below the L with -13+ 10x being above the K. For this we need to find the length of the angle indicated. We must find m

I have a trapeziod @ the top left is L, top right is M, bottom right is N and the bottom left is K. With 12x + 17 is below the L with -13+ 10x being above the K. For this we need to find the length of the angle indicated. We must find m<K?
I'm looking for somebody that will teach me how to do this problem. Give a man a fish he eats for a day. Teach a man to fish, he eats for eternity. At least until all the lakes run dry. lol

First, you need the definition of a trapezoid A quadrilateral which has at least one pair of parallel sides See http://www.mathopenref.com/trapezoid.html In your case, the top (line LM) and the base (line KN) are parallel You need to know about two parallel lines cut by a transversal See http://www.mathopenref.com/anglestransinterior.html Your problem is, after stripping away the irrelevant detail, |dw:1378130757413:dw|
