Best ResponseYou've already chosen the best response.1if its a right triangle then the side would be 12^2+5^2 =13^2 however the angle opposite the misisng side is 41 which is more than 30 degrees and if it was 30 degrees the missing side would be 7.5 so we know for 41 degreees the missing side ha to be greater than that, so its definately not a right triangle, so we have to use law of COSine
