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)}

Wrote an expression gor <br> m &lt; RST
grigory [225]

The expression for the angle m∠RST from the given bisctor is; 6x - 18

<h3>How to find the expression for a given angle?</h3>

From the given image in the attachment we are given that;

SQ bisects ∠TSR

m ∠RSQ = 3x - 9

Now, since  SQ is a bisector of ∠TSR, we can say that

m∠RST = 2 * m∠RSQ

Thus angle RST is expressed as;

m∠RST = 2(3x - 9)

m∠RST = 6x - 18

Slope is how much a graph increases or decreases and is found by counting to the right or left (x axis) and up or down (y axis)

intercepts are determined where points are on the y or x axis and are y = mx + B (it is b)

linear functions and equations can be graphs by y = mx + b or y = mx
