A right triangle is shown. The hypotenuse has length b. The angle opposite to side a is y and the angle opposite to side c is x. Which equations for the measures of the unknown angles x and y are correct? Check all that apply. x = cos–1(StartFraction a Over c EndFraction) x = sin–1(StartFraction c Over b EndFraction) x = tan–1(StartFraction c Over a EndFraction) y = sin–1(StartFraction a Over c EndFraction) y = cos–1(StartFraction c Over b EndFraction)
