Question

SinA=2/3 so what is the value of cosA and tanA

Answer 1

Answer:

cos a =√13/3 and tan a =2/√13

Answer 2

Answer:

Step-by-step explanation:

Sin A =2/3=opposite/hypotenuse.

       (hyp)²=(s)²+(s)².

       (3)²= (2)²+ (s)².

       9-4=s².

      5=s².

      s= √5.  ( adjacent).

     Cos A=adjacent/ hypotenuse.

               = √5/3.

     Tan A=Opposite/adjacent.

               =2/√5.
