property owner thinks he can remove it himself, but is concerned before attempting to cut it down. At 3 P. M. he measures the that it will fall on his greenhouse. He takes several measurements shadow of the tree and finds it to be 15 feet long. He also else must he know to be able to determine the height of the tree? ( 11) the height of the greenhouse the width of the greenhouse (3) the diameter of the tree (4) the speed and direction of the wind (5) the length of the shadow of the 4-foot fencepost​

15 batches are the most you can make

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
