Answer:
The cosine rule tells us that when we have a right triangle, c o s i n e = a h cosine = \frac{a}{h} cosine=ha. The "a" in this case stands for adjacent. The "h" stands for the hypotenuse, which can be found through the pythagorean theorem.
Step-by-step explanation:
As our angle of interest is Sin 0. So accordingly, the Sin function of an angle or Sin 0 Degrees is equal to the ratio of the length of the opposite side to the length of the hypotenuse (longest side).
