 Label it carefully and clearly mark out the quantities that are given and those which have to be calculated. If a person on the ground looks up to the top of a building, the angle formed between the line of sight and the horizontal is called the angle of elevation. The angle of depression from the top of a tower to a boulder on the ground is 38º. Given sin   6 , find cos  90   and sin  90   .

 Identify the appropriate trigonometric ratio to use. If a person standing on the top of a building looks down at a car on the ground, the angle formed between the line of sight and the horizontal is called the angle of depression. If the tower is 25m high, how far from the base of the tower is the boulder 2. 10 Additional Practice- Practice setting up and solving words requiring the use of trig. A ladder 14 feet long rests against the side of a building. A 24 foot ladder leaning against a building forms an 18 degree angle with the side of the building.

Another common type of average problems is the average speed computation.

Coin Problems deal with items with denominated values.

They may also compare the ages involving more than one person.

Average Problems involve the computations for arithmetic mean or weighted average of different quantities.

First, we need to translate the word problem into equation(s) with variables.

Then, we need to solve the equation(s) to find the solution(s) to the word problems.

Supposing that the ground is level, find the vertical distance from the ground to the kite. A wire anchored to the ground braces a 17 foot pole. A jet airplane begins a steady climb of 15 degrees and flies for 2 ground miles. The 600 block of Powell Street in San Francisco has a steep rise.

The wire is 20 feet long and is attached to the pole 15 feet from the base of the pole. If it takes 66 feet along the horizontal for the street to rise 10 feet, find the angle the street makes with the horizontal. A guy wire is attached to a tower at a point 100 feet above the ground.
