Dec 25, 2014 · : Use sine ratio. : Use tangent ratio. : Use Triangle Sum Theorem Example 5: Solve the right triangle. Solution: Even though, there are no angle measures given, we know that the two acute angles are congruent, making them both . Therefore, this is a 45-45-90 triangle. You can use the trigonometric ratios or the special right triangle ratios.
These three other functions are the inverse functions of sine, cosine, and tangent functions. The six trigonometric functions are defined below: Sine: It is defined as the ratio of the opposite side to the hypotenuse of the right-angled triangle. Cosine: it is defined as the ratio of the adjacent side to the hypotenuse of the right-angled triangle.
