Triangle F G E is shown. Angle F E G is a right angle. The length of hypotenuse F G is 15.2 meters and the length of F E is 9 meters. Angle F G E is x. Which equation can be used to find the measure of angle FGE? sin(x) = StartFraction 15.2 Over 9 EndFraction sin(x) = StartFraction 9 Over 15.2 EndFraction cos(x) = StartFraction 15.2 Over 9 EndFraction cos(x) = StartFraction 9 Over 15.2 EndFraction
