In the below figure angle abc is 69 degree, angle acb is 31 degree so find the angle bdc

Step-by-step explanation:

We are given that

We have to find the angle BDC.

In triangle ABC

Sum of interior angles of triangle=180 degrees

Angles subtended on the same are ac are equal.

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.
