#t_e~=3,67" s"#

Explanation:

enter image source here
#""given data:"#

#v_i=36" "m/s" "alpha=(5pi)/6" "t_e=?#
#v_i:"initial velocity"#
#alpha:"projectile angle"#
#t_e:"elapsed time for the projectile"#

#"formula : "t_e=(2*v_i*sin alpha)/g#

#sin((5pi)/6)=0,5#

#t_e=(2*36*0,5)/(9,81)#

#t_e~=3,67" s"#
