    Since it's a quadrilateral, how many degrees in total do the interior angles add up to? :)

    @zepdrix Awh, thanks! yeah, I'm just trying to finish up my math so I can graduate. It's all I have left, I just need a lil help! do they add up to 70 degrees? :)

    lol no silly! :) In a triangle, the interior angles add to \(180^o\). In a quadrilateral the interior angles add to \(360^o\). Since we have a PARALLELOGRAM, the angles opposite one another will be equal.

    If you look at the picture, that means that \(65^o=(2x+3)^o\) because those two angles are opposite one another. Ok ok but let's think a little bit differently, since we don't need \(x\). If that angle is 65, and the angle involving \(x\) is also 65, and we determined that a quadrilateral has 360 degrees total. Hmmmm. So those 2 angles \(65^o+65^o=130^o\) How much does that leave over for the other 2 angles? :D

    @zepdrix is the opposite 65 degrees?

    @Ahsher97 Please be nice to askers, regardless of which grade he/she is in. You have been there at one point. Another way to look at this is by using Interior Angles property (i.e 65+5y =180)

    |dw:1359070814837:dw|This upper angle is also 65 since it's opposite the 65 in a parallelogram. How many degrees does that leave us with for the OTHER two angles if these two are each 65, and a quadrilateral has 360 degrees total? :D

    @zepdrix For these type of questions I wouldn't recommend using the sum of interior angles property, because extra steps are required. Instead use the interior angle property.
