Atunnel is 300 feet deep and makes an angle of 30 with the ground . a.300√3 feetb.300 feetc.600 feet d.100√3 feet

Step-by-step explanation:

The tunnel, the ground and the depth of the tunnel form a right angle triangle.

The length of the tunnel is the hypotenuse of the right triangle that has been formed.

Let the length of the tunnel be .

Using the sine ratio, we obtain;

The length of the opposite side is

We substitute the given values to obtain;

We cross multiply to obtain;

Therefore the correct answer is C.

to determine the unit cost your would divide the total cost by the number sold.
