The slope of the perpendicular line will be the negative reciprocal of the slope of the given line, which is 3/4.
U divide 4/7 by 3/4 which is 16/21
If the variance is 5 then the standard deviation is √5.

Answer:
B
Step-by-step explanation:
We can use the law of cosinse:
= 
− 2ab cos(C)
Suppose the two sides are a and b, and the angle betweent them is C.
= 
− 2*3*4 cos(60)
We can simplify this to get =25-12=13
c=
