Pls help asap 50 pts right answer FOR SURE When the sun is 45 degrees above the horizon and a tree's shadow is 10ft long, how tall is the tree? *
5ft
7ft
10ft
15ft

C

Step-by-step explanation:

Please refer to the attachment below.

So, we essentially have a 45-45-90 triangle.

In the 45-45-90 triangle, the two legs are equivalent.

Therefore, since one of the legs is 10ft, the other leg, the height of the tree, must also be 10ft.

Hence, our answer is C.  

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
