How High and Fast Does a Grasshopper Jump at a 44° Angle?

[Raul-7]

A grasshopper jumps 1.00 m from rest, with an initial velocity at a 44.0° angle with respect to the horizontal.
(a) Find the initial speed of the grasshopper.
(b) Find the maximum height reached.

From the formula I got t=Dx/vi cos 44. Now I do not know how to go on from here.
