Answer:


Step-by-step explanation:

The way the triangle is laid out, BC is the hypotenuse, and AB is the side opposite <C. You hare given that the Sin<C = 1/2

If Sin<C = 1/2 then C = 30 degrees. It is part of the unit circle.

The tan (<30 degrees) = 1/sqrt(3)  from the unit circle.

The cotangent of 30degrees = 1/tan(30) = sqrt(3)

cot(30) = sqrt(3) = 1.7321

An underwater canyon begins at 40 feet
Crazy boy [7]

Answer:

145 feet.

Step-by-step explanation:

Given that:

An underwater canyon begins at depth = 40 ft

Depth of canyon = 105 ft

To find:

The elevation of the bottom of the canyon = ?

Solution:

Kindly refer to the image attached for the given dimensions.

A is the sea level.

B is the point at which the canyon starts and

C is the bottom of the canyon.

As per question statement, we are given that:

AB = 40 feet

BC = 105 feet

And we have to find the distance AC = ?

It is clearly observable that:

AC = AB + BC\\\Rightarrow AC = 40 + 105\\\Rightarrow \bold{AC = 145 ft}

So, the elevation of the bottom of the canyon is <em>145 ft</em>.
