Answer 1

All the areas marked with 1 dash are 144 feet. All the areas marked with 2 dashes are 120 feet.

Answer 2

All we want is the height of the tree though, so we can just use the Pythagorean Theorem.

\(\sf a^2 + b^2 = c^2\)

Where 'a' and 'b' are the two legs of the triangle and 'c' is the hypotenuse.

Can you plug the values in?

Answer 3

You can do it more easily.

Theorem:
The segment that joins the midpoints of two sides of a triangle is parallel to and half the length of the third side.

Answer 4

You can also do it with similar triangles.
