Question

if sin A= 3/4 find cos A and tan A​

Answer 1

Answer:

Cos A =$\sqrt{7}$/4 and Tan A = 3/$\sqrt{7}$

Step-by-step explanation:

Given that sinA=3/4

So  one side of the triangle will be 3k and hypotenuse will be 4k

     so by pythogoras theorem one side will be $\sqrt{7}$k

     so Cos A =$\sqrt{7}$/4 and Tan A = 3/$\sqrt{7}$
