1.	A particle is aimed at a mark which is in the same horizonta plane as the of point of projection. If falls 10 m short of the traget when it is projected of an angle75^(@)of and falls 10m ahead of the target when it is projected with an elevation of 45^(@) . The angle of projection for which the particle exactly hits this targetis (g = 10ms^(-1))
