What is the value of x and y in a 30 60 90 special right triangle

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425

I’m pretty sure the slope would be 1 since the x and y values increase by 1

Really long apparently
