Answer:
<h3>C. 113°</h3>Step-by-step explanation:
(7x - 1) + 79° = 21x + 8
• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.
NRS = 21x + 8
It is parallel, which means that the new line should have the same slope of the given line 
and the slope is the coefficient of x
so the slope = -5/4
in order to solve this problem we have to know the equation of the slop
where (x1,y1) is the point by which the new line passes through
-5(x-1)=4(y+4)
-5x +5=4y+16 (by subtracting 16 from both sides)
-5x -11= 4y (divide both sides by 4)
y=
and the slope is the coefficient of x
so the slope = -5/4
in order to solve this problem we have to know the equation of the slop
where (x1,y1) is the point by which the new line passes through
-5(x-1)=4(y+4)
-5x +5=4y+16 (by subtracting 16 from both sides)
-5x -11= 4y (divide both sides by 4)
y=
