Dvinal [7]
I think you’re answer is 42 slices of pizza.

the way i worked it out is by finding out how many minutes are in an hour (60 mins). after that i divided it by 10(mins), which would have gotten me 6. therefore i multiplied 7 x 6 which gave me 42.

Trig question ———————
Stels [109]

Answer:

1) \cos(A)  = 0.948(appx)

2) \sin(A)  = 0.316(appx)

3) \tan(A)  = 0.333(appx)

Step-by-step explanation:

Using Pythagorean theorem ,

Hypotenuse =

\sqrt{ {6}^{2} +  {2}^{2}  }  =  \sqrt{36 + 4}  =  \sqrt{40}  = 2 \sqrt{10}

We know that

  • \sin( \alpha )  =  \frac{side \: opposite \: to \:  \alpha }{hypotenuse \: of \: triangle}
  • \cos( \alpha )  =  \frac{side \: adjacent \: to \:  \alpha }{hypotenuse \: of \: triangle}
  • \tan( \alpha )  =  \frac{side \: opposite \: to \:  \alpha }{side \: adjacent \: to \:  \alpha }

Where \ alpha is an angle of tge triangle.

In the triangle given above , \ alpha = angle \: A . So,

1) \cos(A) = \frac{6}{2 \sqrt{10} }  =   \frac{3}{ \sqrt{10} }  = 0.948(appx)

2) \sin(A) = \frac{2}{2 \sqrt{10} }  =   \frac{1}{ \sqrt{10} }  = 0.316(appx)

3) \tan(A) = \frac{2}{6}  =  \frac{1}{3}  = 0.333(appx)
