    Hello, ProMathematics!

    Find angle e.

    This is a Parallelogram. NOT a triangle!!!
    . . It is not a pentagon either ... so what's your point?

    Code:
                *  *  *  *  *  *  *
               *  *              *
              *     *           *
             *        *        *
            *           * 93' *
           * 35'        e *  *
          *  *  *  *  *  *  *

    We're expected to know this fact:
    . . Adjacent angles of a parallelogram are supplementary.

    Hence: . 35^o + (e + 93^o) \;=\;180^o

    Now solve for e.

    But, each pair of angles between 2 parallel sides add up to 180''. SO???? This is like <e= 180''-(92+35) = 53''
    Is this the way to do it? If yes, YOU ARE MY SAVIOR TODAY!!!!
