Since it's a quadrilateral, the total angle is 360. And the two angles at the sides are equal.

sarahc · Answer

what would be the formula?

anonymous · Answer

The sides and angles of a kite:


There are two sets of adjacent sides (next to each other) that are the same length (congruent.)
=
There is one set of congruent angles.  These are opposite of each other and are between sides that are different lengths.

anonymous · Answer

so the total angle of a quadrilateral is 360 in order to get angle E AND G THAT ARE SAME LET IT BE X SUBTRACT 360-109-41=2X
                                   210=2X
                                    X=105
