Question

if tan A = 24 by 7 and A is in the 3rd quadrant then find the value of sin A and cos A​

Answer 1

Answer:

sin A=24 by 25 and cos A =7 by 25

Step-by-step explanation:

In this rt triangle tan A =24 by 7.It means hypotenuse is 25x.

sin A=opp .side by hypotenuse.

And it is24 by 25.

cos A=adj.side by hypotenuse.

And it is 7 by 25.

Answer 2

Answer:

sin A= -24/25 and cos A = -7/25

Step-by-step explanation:

tan A = 24/7 = y/x

A E quadrant 3

So y= -24 and x= -7

hence, r = 25

Therefore, sinA = y/r = -24/25

and cosA= x/r= -7/25
