Question

IF sin A =3 then find cos A and tan A​

Answer 1

Step-by-step explanation:

we can do this by basics of trigonometry

sinA=opposite / hypotenuse

so 3 is opposite and 1 is hypotenuse

we can say that square of the opposite and adjacet equal to hypotenuse square

8

so cosA is equlal to 8 and tanA is equal to sinA/cosA

=3/8
