$$\sin 45^\circ=\frac{-1}{\sqrt{2} }, \ \cos45^\circ=\frac{1}{\sqrt{2} }, \ \ \tan 45^\circ=-1$

Solution:

In the given right triangle,

θ = 45°

Opposite side to θ = –1

Adjacent side to θ = 1

Hypotenuse = $\sqrt{2}$

Using basic trigonometric ratio formulas,

$$\sin \theta=\frac{\text { Opposite }}{\text { Hypotenuse }}$

$$\sin 45^\circ=\frac{-1}{\sqrt{2} }$

$$\cos \theta=\frac{\text { Adjacent }}{\text { Hypotenuse }}$

$$\cos45^\circ=\frac{1}{\sqrt{2} }$

$$\tan \theta=\frac{\text { Opposite }}{\text { Adjacent }}$

$$\tan 45^\circ=\frac{-1}{1}=-1$

Therefore,

$$\sin 45^\circ=\frac{-1}{\sqrt{2} }, \ \cos45^\circ=\frac{1}{\sqrt{2} }, \ \ \tan 45^\circ=-1$

Okay so there are 8 employees and 200 calls per hour for all in 8 hours then all you need to do is multiply the 200 calls per hour by the 8 employees
200 divided by 8 is 25 and 25 times 8 is 200 so each employee makes 200 calls in their work day
i really hope i helped you out in some type of way :)))
