Cameron launches a toy plane from the roof of the school building, which is 84 feet high. The plane's height above the ground is modeled by the function .h=-16t^2+32t+84
d) Unfortunately, Cameron's plane took a nosedive and crash-landed on the ground. Always looking on the bright side, Cameron decided to figure out how long his plane was in the air before it crash-landed.
How long was Cameron plane in the air before it crash-landed? you MUST clearly explain all the steps you took to find the solution
Plz give a good step by step explanation

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

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.

yes.. it's proven to be 36.
