Answer:

The correct option is B)
$c=(5)/(\cos35^0)$ .

Explanation:

Consider the provided information.

Angle A C B is 90 degrees and angle A B C is 35 degrees.

The required figure is shown below:

We need to find the value of c.

Use the trigonometric function:
$\cos\theta=(Adjacent)/(Hypotenuse)$

$\cos35^0=(5)/(c)$

$c=(5)/(\cos35^0)$

Hence, the correct option is B)
$c=(5)/(\cos35^0)$ .
