Answer:
D. Shari is standing 50 feet from a tree that is 100 feet tall. what is the distance between Shari’s foot and the top of the tree
Step-by-step explanation:
When we want to calculate the distance between Shari’s foot and the top of the tree, we apply the Pythagorean Theorem as follows.
[tex]h^2=50^2+100^2\\h^2=12500\\h=\pm \sqrt{12500} \\h=\pm 111.8\\h=|\pm 111.8|\\h=111.8$ feet[/tex]
Recall, there is always a plum/minus sign before the square root symbol. This is as a result of the fact that:
[tex](-a)^2=a^2\\a^2=a^2[/tex]
However, since we are looking for distance, we ignore the negative sign by making use of the absolute sign.
The correct option is D
