Answer with Step-by-step explanation:

We know that

sinФ=Perpendicular/hypotenuse and cosФ=Base/hypotenuse

Now, we have to calculate the value of sin A and cos A

As we can see from the graph Perpendicular=8

Base=6

and Hypotenuse=10

Hence, sin A=8/10=0.8

and cos A=6/10=0.6

Hence, exact value of sin A=0.8 and exact value of cos A=0.6

I hope this helps

sinA=BC/AB

sinA=8/10=0,8

cosA=AC/AB

cosA=6/10=0,6
