Best ResponseYou've already chosen the best response.0use substitution method. let sin x be whatever variable you'd like like a. therefore you'd get: \[75 a ^{2} 34 a+3=0\] then factor, if factoring doesn't work use quadratic formula. as for finding the angle follow the directions and approximate the angle x.

Best ResponseYou've already chosen the best response.0don't forget when you get to the when you're done factoring that remember that you are solving for x so replace variable a with sin x.
