Answer:

Explanation:Sin Cos formulas are based on sides of the right-angled triangle. Sin and Cos are basic trigonometric functions along with tan function, in trigonometry. Sine of angle is equal to the ratio of opposite side and hypotenuse whereas cosine of an angle is equal to ratio of adjacent side and hypotenuse.

Sin θ = OppositesideHypotenuse

Cos θ = AdjacentSideHypotenuse
