A sector of a circle is like a slice of pizza or pie. Finding the perimeter, or the distance around the outside edge, can be a little tricky. In... Finding the perimeter, or the distance around... Trigonometry; Sine and Cosine Rule; Sine and Cosine Rule . This section looks at the Sine Law and Cosine Law. The Sine Rule . The Law of Sines (sine rule) is an important rule relating the sides and angles of any triangle (it doesn't have to be right-angled!): If a, b and c are the lengths of the sides opposite the angles A, B and C in a triangle, then: a = b = c sinA sinB sinC. If you wanted

Find the area of a kite with the given length 2 and breadth 3 using Trigonometry Method. Step 1: Find the area. Area = a * b * SinC = 2 * 3 * Sin(33) = 6 * 1 = 6. Case 3: Find the perimeter of a kite with the givenlength 2 and breadth 3. Step 1: Find the perimeter. Perimeter = 2(a + b) = 2(2 + 3) = 2(5) = 10. The above example will clearly illustrates how to calculate the Area, Perimeter of a... Trigonometry: using sin, cos and tan As mentioned in the topic overview, you can use the trigonometric functions sin, cos and tan to find the length of the sides of a triangle; the hypotenuse, opposite and adjacent, as well as unknown angles.
