Problem 1 :
The angle of depression from a kookaburra’s feet to a worm on a ground is 40°.The worm is 15 meters from a point on the ground directly below the kookaburra's feet.
How high above the ground are the kookaburra's feet, correct to the nearest meter?
Problem 2 :
Danni is flying a kite that is attached to a string of length 80 meters. The string an angle of 55° with the horizontal. How high, to the nearest meter, is the kite above Danni's hand ?
Problem 3 :
The plane flies on a bearing of 150° from A to B.
What is the bearing of A from B ?
Problem 4 :
Two trees on a ground level, 12 m apart are joined by a cable. It is attached 2 meters above the ground on one tree and 11 meters above the ground to the other.
What is the length of the cable between the two trees ?
Problem 5 :
What is the area of the triangle ?
Problem 6 :
Three towns P, Q and R are marked to the diagram. The distance from R to P is 76 km. ∠RQP = 26° and ∠RPQ = 46°
What is the distance between P to Q to the nearest km ?
Problem 7 :
Town B is 80 km due north of Town A and 59 km from Town C. Town A is 31 km from Town C.
What is the bearing of Town C from Town B ?
Problem 8 :
What is the size of the smallest angle in the triangle ?
1) the kookaburra is approximately of 13 m height.
2) the required height is approximately 66 m.
3) Bearing of A from B = 330
4) the length of the cable is 15 m.
5) Area of the triangle ABC = 41.64 m^{2}
6) the required distance between P and Q is 165.01 km.
7) the required bearing is 159.
8) the required angle measure is 75.52.
