Answer:
The angle between the 190 ft. side and the 330 ft. side is 
Step-by-step explanation:
<u>The Law of Cosines</u>
When we know the value of all sides of a triangle, we can compute all of its interior angles by using the Law of Cosines, which is a generalization of the Pythagoras's theorem. If a,b, and c are the known sides of a triangle and
is the angle formed by sides a and b (opposite to c), then

We'll use the values a=190, b=330, c=280 because we want to compute the angle opposite to c

<h3>What is angle bisector?</h3>
Angle bisector in geometry refers to a line that splits an angle into two equal angles. Bisector means the thing that bisects a shape or an object into two equal parts.
Given:
AT bisects <MAR
and, m<MAT= (6x-4) and and m<RAT = (2x+8)
As, <MAR is bisected by ray AT.
So,
<MAT = <RAT
6x-4= 2x+8
6x- 2x = 8+4
4x = 12
x= 3
So, <MAT = 6x-4= 6*3-4= 14
and, <RAT = 2x+8 = 14
Hence, MAR= <MAT + <RAT = 14+14=28

In order for two lines to be parallel, the slope of the equations have to be the same.
y = 3/4x + 7 —> 3/4 is the slope.
For the new equation, the line has to go through (-12,36) which means that the y- intercept has to be 36.
The new equation would be y = 3/4x + 36.
Here is a graph to prove my point.
The red one is the original, the blue one is the one parallel to the original.
Hope this helped:$
