The four angles inside EVERY four-sided figure add up to 360 degrees, no matter what the shape of the figure is.
"Four obtuse angles" means "four angles of more than 90 degrees each".
(four times more-than-90) = more than 360
so NO 4-sided figure can have four obtuse angles inside it.

You multiply .65 times 100 and you get 65 which is 65% of 100

6 - (-6)
This is because two negatives make a positive, so you’ll be adding 6+6 which equals to 12 not 0
