A man on the deck of a ship is 16m above the water level. He observes that the angle of elevation of the top of a cliff is 45 degree and the angle of depression of the base is 30 degree.Calculate the distance of the cliff from the ship and the height of the cliff.
Plz fast with all details and figure.

tan30 = y / distance
1/√3 = 16 / distance
distance = 16√3
tan45 = x / distance
x = 16√3
height of the cliff = X+Y
height of the cliff = 16+16√3
H=16(2.732)
H= 43.712 m
1/√3 = 16 / distance
distance = 16√3
tan45 = x / distance
x = 16√3
height of the cliff = X+Y
height of the cliff = 16+16√3
H=16(2.732)
H= 43.712 m
