A projectile is launched from the ground with velocity |v→|= 8 m/s, at an angle θ from the horizontal direction. The projectile would have landed on the ground at the horizontal distance d1 away from the launch point, but instead it hit the top of a platform of height h in the way. The platform was hit at a horizontal distance d2 away from the launch point.

If it takes ttop = 0.54 seconds for the projectile to reach the top of its trajectory, what is the value of the launch angle θ ? Use g = 9.8 m/s2 and retain one decimal place for you answer.
