Question

a submarine is a type of watercraft define to function underwater here a submarine at the surface of an Ocean makes an emergency dive, its part making an angle 30 degree with the surface if it goes 300m long its downward path, how deep will it be??????





answers please brothers and sisters.....!!!!!​

Answer 1

Answer:

It makes 30 degrees with the surface. Let x be the depth and 300m is hypotenus of the right angled triangle.

Tan30=x/100

1/square root3=x/100

x=100*root3 m

Step-by-step explanation:

Answer 2

The depth of a submarine is 259.80 meters or $150\sqrt{3}$.

Step-by-step explanation:

Given that submarine makes an angle of 30 degrees when it make a emergency dive. And submarine goes downward AB=300.

Now we have to calculate the depth of submarine,

Let in triangle ABC, AB is the hypotenuse, AC and BC are perpendicular and base respectively.

In triangle ABC

$\angle BAC=30^{\circ}$

Now,

$AC=300\cos 30^{\circ}\\\\300\frac{\sqrt{3}}{\sqrt{2}}\\\\150\sqrt{3}\\\\AC=259.80m$
