Answer :


In the first case:

Height of slide= 1.5 m and angle of elevation = 30°

Now,


where p = perpendicular, i.e. height of the slide and h = hypotenuse, i.e. length of the slide and θ is the angle of elevation



Hence, h = 3 m


In the second case:


Height of slide, = 3 m, angle of elevation = 60°





Hence, h = 2 m


Therefore, the length of the slide in the first case and the second case are 3 m and 2respectively.
