Answer:

The midpoint of the segment is (6,5)

Step-by-step explanation:

To find the midpoint of a segment we use the formula

midpoint = (x1+x2)/2, (y1+y2)/2

= (10+2)/2 , (7+3)/2

= 12/2, 10/2

=6,5

The midpoint of the segment is (6,5)

For this case what we must do is use the law of cosines.
We then have the following equation:
$c ^ 2 = a ^ 2 + b ^ 2 - 2 * a * b * cos (x)
$
Where,
a, b: sides of the triangle
x: angle between sides a and b.
Substituting values we have:
$c^2 = 90^2 + 75^2 - 2*90*75*cos(85)
$
Clearing the value of c we have:
$c = \sqrt{ 90^2 + 75^2 - 2*90*75*cos(85)}$
Answer:
An expression that is equivalent to how many feet the oak trees are from each other is:
$c = \sqrt{ 90^2 + 75^2 - 2*90*75*cos(85)}$
