Does anyone know the answer to this question

ANSWER

\cos B = \frac{ \sqrt{3} }{3}

EXPLANATION

The given triangle is a right triangle.

It was given that,

a = 1

and

b =  \sqrt{2}

Using the Pythagoras Theorem, we can determine the value of c.

{c}^{2}  =  {( \sqrt{2} )}^{2}  +  {1}^{2}

{c}^{2} = 2 +  1

{c}^{2} = 3

c =  \sqrt{3}

The ratio is the adjacent over the hypotenuse.

\cos B =  \frac{1 }{ \sqrt{3} }

We rationalize to get:

\cos B =  \frac{ \sqrt{3}  }{ \sqrt{3}  \times  \sqrt{3} }  =  \frac{ \sqrt{3} }{3}

5x14=70

Therefore, it takes 70 seconds to fold 5 shirts.
