I think it might be r= -3
The formula for the law of sines is:
sin(A)/a = sin(B)/b = sin(C)/c
Big letters denote angle measures while smaller letters denote side lengths.
Answer:

Step-by-step explanation:
The limit is:

so, you have an indeterminate result. By using the l'Hôpital's rule you have:

by replacing, and applying repeatedly you obtain:

hence, the limit of the function is -1/14
We use quadratic formula for that one
remember that √-1=i
so
for
ax^2+bx+c=0

so
given
5x^2-6x+2=0
a=5
b=-6
c=2
