Answer:
See attached photo.
Step-by-step explanation:
x = -2y^2 + 4y + 2
I don't know if this is right, but I'm pretty sure it's B.
If two angles are equal, then the two angles are obtuse.
If we are to connect the root of the tree to a person to the top of the tree, we form two right triangles. If we let x and and 200 - x be the distance of Harris and Annabelle from the tree, respectively and h be the height, we form the trigonometric functions,
tan 30° = h/x
tan 35° = h/(200 - x)
The values of h and x in the equations are 63.28 ft and 109.62 ft, respectively. Thus, the answer to this item is approximately 63.28 ft.
