To find LM, the longest side and hypotenuse, I can use a lot of methods, I will show just one
adjacent of angle NLM (LN)/hypotenuse (LM) is cos
x= about 23.262961976 units

hope this helps..
Good luck on your assignment..
(c) it has 4 congruent angles.
a parallelogram is a four sided figure in which opposite sides are equal and parallel.
with is description we ca say that:opposite sides are congruent. diagonals bisect each other. consecutive angles are supplementary.
the consecutive angle add up to 180°. that means that they are supplementary.
the 4 angles are not congruent.
recall the angle sum identities:
then the left hand side of the equation reduces significantly to give
in general, this occurs for and where is any integer. we get solutions in the interval for , for which we get
