    Re: Parallelogram find angels

    Sure, here's the definition of an acute angle:
    An acute angle ("acute" meaning "sharp") is an angle smaller than a right angle (it is less than 90 degrees).

    I believe this is a trick problem designed to test your knowledge of definitions. There is no parallelogram where the acute angle is greater than 90 degrees because that would violate the definition of acute.

    It's hard to translate it to English but.. The height line drawn from parallelogram acute angle is 130. Find parallelogram other corner angles.
    Parallelogram find angels-asdasa.png I think it's meant to be something similar and from that I have to find other angles.

    I see. $\dfrac{360-2\times 130}{2} =50^\circ$ are the two adjacent angles while the opposite angle is 130 degrees. Ignore the height.
