Question

standing on the Deck of the ship which is 40 metre above the water level he observes the angle of elevation of the top of the equal to 60 degree and the angle of elevation and depression of the base of files has 30 degree calculate the distance on the hills hills from the ships and then height of the hill root 3 equal to 1.732​

Answer 1

Answer:

Step-by-step explanation:

Distance between the Ship and hills = X

tan 30 = 1/√3 = 40/ X

X = 40√3 = 69.28m

Height of hills = Y

tan 60 = √3 = Y-40/ 69.28

Y - 40 = 120

Y = 160m
