There is no solution

We attempt to use the law of sines to solve the triangle.
The law states:
#a/sin(A) = b/sin(B) = c/sin(C)#

#18/sin(76) = 20/sin(B)#

#20*sin(76) = 18*sin(B)#

#20/18 * sin(76) = sin(B)#

#arcsin(20/18 * sin(76)) = B#

#B = arcsin(1.078)#

#B =# error

Therefore, there is no solution.
