Question

Find sin S, sin R, cos S, cos R.sin S =sin R =cos S =cos R =

Answer 1

From the basic knowledge of Trignometry,

We are meant to find sin S , sin R , cos S and cos R:

sin S = opposite / Hypoteuse = 18 / 26

sin R = opposite / Hypotenuse = 16 / 26

cos S = Adjacent / Hypotenuse = 16 / 26

cos R = Adjacent / Hypotenuse = 18 / 26
