Solution

Sines and Cosines:
There are the two fundamental terms of Trigonometry, So-called Sin and Cos.
$\sin (θ)$ is the ratio of the opposite side to the hypotenuse, while $\cos (θ)$ is the ratio of the adjacent side to the hypotenuse.
Here, If we taking angle $A$ then Trigonometric ratios Sine And cosine are as
Hence, $S i n (∠ A) = \frac{O p p o s i t e}{H y p o t e n u s e} a n d C o s (∠ A) = \frac{A d j e c e n t}{H y p o t e n u s e}$
