Use the Law of Sines to solve triangle ABC when a=1.43,b=4.21,and A=30.4 degrees. If no solution exists, rite none.

make sure you have a diagram to show the given information.

(At this point you should realize that it is not possible to draw the figure !)

so try the math...
sinB/4.21 = sin 30.4º/1.43
sinB = 1.49, but this is impossible since the since of any angle lies between -1 and +1.

So "no solution"

PS. I still write "write" as 'write' and not "rite", since that would not be right.
