Help! Find the value of x.

30 degrees

Step-by-step explanation:

the sum of a triangles angles needs to be 180 and since its an equilateral, all angles are the same so if each angle is 60 degrees do

60 / 2 = x

x = 30

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.
