This is my last one please help you need to explain it just tell me the right answer thank you

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

the answer is 5/14.

hope this .
