Assuming that this happened at the same environment like the time of day, then we can use ratio and proportion. We relate the height of the tree with its shadow by using the ratio of the biologist's height to his shadow.
Height of tree/Height of its Shadow = Height of biologist/Height of his Shadow
Height of tree/28 = 7/2
Height of tree = 7*28/2
Height of tree = 98 feet
The answer is D.
Answer:
20
Step-by-step explanation:

I believe it would be negative three (-4) since the lines are thinner however; there is a chance they are skip counting by 2. In that case the answer would be negative six (-6).
Find the ratio of the known sides 10 and 12
12/10 = 1.2
The larger kite is 1.2 times the size of the smaller kite.
Multiply 7 by 1.2:
x - 7 * 1.2
x = 8.4
