Q1. The angle of elevation from a yacht to the top of a cliff is 18o. If the yacht is 1.7km from the base of the cliff, find how high the cliff is. Q2. The pilot of a rescue helicopter spots a swimmer in distress at an angle of depression of 12o.
An angle is named either its vertex, after its rays, or the amount of rotation between the two rays. For example, an angle can be denoted ∠𝑨𝑨, ∠𝑩𝑩𝑨𝑨𝑨𝑨, or ∠𝜽𝜽, where the sign ∠ (or ∡) simply means an angle. Notice that in the case of naming an angle with the use of
3.5: Trigonometric Functions Reference Evans 6.1 Consider a right-angled triangle with angle θ and side lengths x, y and h as shown: θ x y h The trigonometric functions sine, cosine and tangent of θ are defined as: sinθ = opposite hypotenuse = y h, cosθ = adjacent hypotenuse = x h tanθ = opposite adjacent = y x = sinθ cosθ 71

Worksheet 2:8 introduces the trig ratios of sine, cosine, and tangent. To review the ratios, consider a triangle ABC with angle ˚ as marked. b c a ˚ A C B The hypotenuse (hyp) of the triangle is c; the adjacent (adj) side is b; the opposite (opp) side is a. The side of length a is opposite the angle, and the side of length b is the side ...
