please check my answer
determine the number of possible solutions if A=62, a=4 and b=6
I got B
a)none
b)one
c)two
d)three
from you "diagram" you have the ambiguous case
sinB/6 = sinA/4
sinB = 6sin62°/4 = 1.32..
but the sine of any angle cannot be greater than 1,
so the triangle is not possible or there is no solution
