The equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
(3,1) and m=3
y-1=3(x-3)
y-1=3x-9
y=3x-8
        
             
        
        
        
Answer:
Option A) m∠RNS=27°
Step-by-step explanation:
We know that  ∠UNR = 180°. This tells us that the Sum of the enclosed angles should equal 180°, by trigonometry. So the enclosed angles are:
∠UNR = 180°. This tells us that the Sum of the enclosed angles should equal 180°, by trigonometry. So the enclosed angles are:
 ∠RNS =
∠RNS = 
 ∠SNT=
∠SNT= 
 ∠TNU=
∠TNU= 
Now let us add all the angles and solve for the value of  as follow:
 as follow:


Now lets plug in the value into the expression for angle  ∠RNS to find the angle as:
∠RNS to find the angle as:

Thus Option A. is the correct answer.
