Ihave only 2 right angles and no line segments of equal length. what type of quadrilateral could i be? draw an example.

Well to be honest if u had shown 2 angles it would have helped but i have come across these type of questions and i have drew a kite or trapizuim. If not sorry!

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4
