8 – 6 The Sine and Cosine Ratios. Sine and Cosine Suppose you want to fine the legs, x and y, in a triangle. You can’t find these values using the tangent.
Date: Topic: Trigonometric Ratios (9.5). Sides and Angles x The hypotenuse is always the longest side of the right triangle and is across from the right.
Basic Trigonometry. Parts of a Right Triangle Imagine that you are at Angle A looking into the triangle. The adjacent side is the side next to Angle A.
(1) Sin, Cos or Tan? x 7 35 o S H O C H A T A O Answer: Tan You know the adjacent and want the opposite.

7.2 Finding a Missing Side of a Triangle using Trigonometry.
Trigonometry can be used for two things: 1.Using 1 side and 1 angle to work out another side, or 2.Using 2 sides to work out an angle.
Trigonometry in Rightangled Triangles Module 8. Trigonometry A method of calculating the length of a side Or size of an angle Calculator required.
A = Cos o x H Cosine Rule To find an adjacent side we need 1 side (hypotenuse) and the included angle. A = Cos ° x H A = Cos 60° x 9 A = 0.5 x 9 A = 4.5.
There are 3 kinds of trigonometric ratios we will learn. sine ratio cosine ratio tangent ratio Three Types Trigonometric Ratios.
