18. In a kite ABCD, AB=AD and CB=CD, If`/_A 108^@` and `/_C=36^@` then the ratio of the area of triangle ABD to the triangle CBD an be written in the form `(a-btan^2(36^@))/c` where a,b,c are relatively prime numbers. Determine the ordered triplet (a,b,c) 2 then the ratio of 2 then of the area of AABD to thethe ratio
