Question

if tan theta is = 1 upon 2 root 2 then find the value of sin theta and Cos theta​

Answer 1

Answer:

tan theta =prpendicular/base =√2/1

then prpendicular=√2k

        base=1k

hypotenuse=(√²k)²+(1k)²

                   =2k²+1k²

                    =3k²

now , sin theeta=prpendicular / hypotenuse

                            =√2k²/3k²

                             =√2/3

cos theeta=base/hypotenuse

                  =1k/3k

                   =1/3
