Find sin S, sin R, cos S, and cos R.

sin S = 9/13

sin R= 8/13

cos S= 8/13

cos R= 9/13

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

i believe the answer is c.
