d) 123

Step-by-step explanation:

123 as,

angle CDA =57 and angle BCD = 180 - CDA (They form a linear pair)

So, BCD = 180 - 57

Hope this helps you, mark me as brainliest please, Thank you

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 your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
