In concave kite ABCD, there is an interior angle at vertex B that is a reflex angle. Given that m∠A = m∠C = m∠D = 30° and the length of side AB is 3 in, find the length (in inches) of AC(not shown).

x = 25/2304

step-by-step explanation:

the answer is c.

perimeters = 3√10/5

areas = 90/25

i got it down chief.
