12/13

Step-by-step explanation:

First, use the pythagorean theorem to find EF

5^2 + EF^2 = 13^2

You get: EF = 12

Sin is opposite over hypotenuse. 12 represents the opposite and 13 represents the hypotenuse.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

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.
