WebThe law of cosines relates the three sides of the triangle to one of the angles. You can use it in a couple of ways. First, if you know one angle and the two adjacent sides, then you can determine the opposite side. For instance, if angle C = 60°, side a = 5, and side b = 8, then the law of cosines says c2 = 25 + 64 – 80 cos 60°. WebTherefore we use the Sine Rule. e.g. 2: The triangle is right-angled. The question involves angles. Therefore we use trig ratios - sin, cos and tan. e.g. 3: The triangle is right-angled. The question does not involve angles. Therefore we use Pythagoras's Theorem. e.g. 4: The triangle is not right-angled. We do not know a side and its opposite ... robing allowance

Web8 apr. 2024 · The law of sines is described as the side length of the triangle divided by the sine of the angle opposite to the side. The formula for the sine rule of the triangle is: a s i n A = b s i n B = c s i n C (where a, b, c are sided lengths of the triangle and A, B, C are opposite angles to the respective sides) WebCalculation of side c is straightforward, but calculation of sides a or b is more involved since changing either side c or angle C forces changes in both a and b. To calculate a or b, first use the law of sines to find the angle opposite the side you wish to calculate. Then use the law of cosines to find the unknown side length.
