Given:- AC = 33

⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀BC = 44

⠀⠀⠀⠀⠀AB = 55

⠀⠀⠀⠀⠀

⠀⠀⠀⠀☆Values of Sin A and Cos A☆

-› For Angle A

BC becomes the perpendicular and AC becomes the Base while AB is the hypotenuse.

Here, p denotes the perpendicular, B denotes the base while H stands for hypotenuse.

$sin \: a = \frac{p}{h}$

$sin \: a = \frac{44}{55} \\ \\ = \frac{4}{5}$⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀

$cos \: a = \frac{b}{h}$

$cos \: a \: = \frac{33}{55} \\ \\ = \frac{3}{5}$

Hence, the values of sin A and cos a is

$\frac{4}{5} and \: \frac{3}{5}$
