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)}

11. Mis the midpoint of QR. Q is at (-8, 2) and M is at (4, -3). Find the coordinates of the endpoint R.​
tamaranim1 [39]

Answer:

R(16,-8)

Step-by-step explanation:

if (x1,y1) and (x2,y2) are coordinates of two points and (x,y) the coordinate of midpoint.

then x=(x1+x2)/2

and y=(y1+y2)/2

let coordinates of R are (x,y)

4=(-8+x)/2

8=-8+x

x=8+8=16

-3=(2+y)/2

-6=2+y

y=-6-2=-8

so R is (16,-8)
