You'd use the equation y2-y1/x2-x1
0-(-3)/-7-5 = 3/-12 = -1/4
So -1/4 would be the slope
m= -1/4
Use the law of cosines to find a:

So to use the given numbers you get:

Which would come out to equal about 35.94
so a=35.9
Answer:
r = 6 in
Step-by-step explanation:
=
r²h/3 = 216
r² (18/3) = 6 r² = 216
r² = 216/6 = 36
r = 6
The answer is n>2. ......
