Y= 10 because you have a 180 degree angle split in half which equals 90 degrees so 3•30=90 the the other side has to equal 90 degrees so 2•30=60 then 3•10=30 so then just add 60 and 20 and there is your 90

A tank's length is 3 feet longer than its width. The height is 1 foot less than the width. The volume of the tank is 160 cubic f
Ivanshal [37]

Answer:

The width of the tank is <u>5 feet</u>.

Step-by-step explanation:

Given:

A tank's length is 3 feet longer than its width.

The height is 1 foot less than the width.

The volume of the tank is 160 cubic feet.

Now, to find the width of the tank.

Let the width of the tank be x.

So, length is x+3.

And, height is x-1.

The volume of tank = 160 cubic feet.

Now, to get the width we put formula:

Volume = length × width × height.

160=(x+3)\times x\times (x-1)

160 =x(x^2-x+3x-3)

160=x(x^2+2x-3)

160=x^3+2x^2-3x

<em>Subtracting both sides by 160 we get</em>:

0=x^3+2x^2-3x-160

x^3+2x^2-3x-160=0

Now, on solving the equation we get:

x=5.

The width = 5 feet.

Therefore, the width of the tank is 5 feet.
