What went wrong?

The mistake that occurred was that the person trying to solve the problem did not cross multiply correctly. They did seem to cross multiply, but only one side which was the 4.21 × sin(30.4) and then they equaled it to the answer they got(2.13). This was where the mistake occurred because they were supposed to cross multiply both sides. Then they had to divide the 1.43 to both sides which then would have led them to getting 1.48 and finally to the answer which was no possible answer.Since they started off the problem wrong it led them to having all the problem wrong.

What they should have done:
