The answer to the first one is 72.
Rhombus or diamond I think. I hope that this helps!
i think that that the answer is 13 Step-by-step explanation:
B is 747.7 ..................
Since it’s a trapezoid, 111 + b will equal 180, as will 41 + a.
111 + b = 180 means b = 69.
41 + a = 180 means a = 139.
This happens simply because two angles that are positioned that way between parallel lines will always be supplementary. It’s also worth noting that all angles in any quadrilateral will add up to be 360 degrees.
