Need Verification on Physics Problem?

Just want to know if I am right or wrong, do not want an answer if I am wrong...maybe a hint, like what equation I need, etc.

If a grasshopper jumps a distance of .76m from rest at a 30 degree angle, what jump speed is needed to achieve the stated distance?

I used the equation (X)f= (V)i²[sin(2?)]/g and rearranged it to give me: (V)i²= .76m(9.8m/s²)/sin(2x30) which gave me 8.6m²/s². Taking the sq. root gives 2.9m/s. Thanks for any feedback.
