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

PLEASE HELP ive been stuck on this for a long time

Answer:

Below

Step-by-step explanation:

You can use Pythagorean theorem to find the hypotenuse of a right triangle.

a2 + b2 = c2

The square root of 15 = 3.8729.... (a bunch of other numbers)

4^2 + 3.8729^2 = c2

16 + 15 = 31

Now that you have this, you need to find the square root

The square root of 31 = 5.56775436

Rounding this to the tenth it would be: 5.57

Final answer: C = 5.57

hope this helps! :)
