Solution

(12) A string of a kite is 100 meters long and it makes an angle of 60° with horizontal. Find the height of the kite,assuming that there is no slack in the string.

Solution

(13) The angle of elevation of the top of a tower at a distance of 130 m from its foot on a horizontal plane is found to be 63°. Find the height of the tower.

Solution

(14) A ladder is leaning against a vertical wall makes an angle of 20° with the ground. The foot of the ladder is 3 m from the wall.Find the length of ladder.

Solution

(15) A kite flying at a height of 65 m is attached to a string inclined at 31° to the horizontal. What is the length of string.

Solution

(16) The length of a string between a kite and a point on the ground is 90 m. If the string is making an angle θ with the level ground  such that tan θ = 15/8, how high will the kite be?

Solution
