Ineed this question answered now with a mini explanation

100°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

∠ACB = 180° - (90 + 50)° = 180° - 140° = 40°

∠ECD = 40° ( vertical angle to ∠ACB )

Since CE ≅ ED then ΔCDE is isosceles and

∠CDE = ∠ECD = 40°

∠E = 180° - (40 + 40)° = 180° - 80° = 100°

step-by-step explanation:

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.
