Solution: in this triangle, we need to find the lengths of two sideswe can find the length of one side using a trig ratio then we can find the length of the third side either using a trig ratio, or the pythagorean theorem.
Maths tutorial: trigonometry law of sines / sine rule find this pin and more on math by dirk wagner maths tutorials, geometry and trigonometry the law of sines (also known as the sine rule) is a method for working out the angle or side length in a non righ. Trigonometric equations and identities part 1: pythagorean identities recall that, in the section on the unit circle, we established that given any angle $\theta$, $\left(\cos\left(\theta\right),\sin\left(\theta\right)\right)$ are the coordinates of a point on the unit circle. Transform the given trig equation into a trig equation having only one unique trig function as variable there are a few tips on how to select the appropriate variable the common variables to select are: sin x = t cos x = t cos 2x = t, tan x = t and tan (x/2) = t.
