A surveyor wants to know the length of a tunnel built through a mountain. According to his equipment, he is

MrMuchimi

Answer:

Length of the tunnel is 51.7 meters

Step-by-step explanation:

We are given that,

The surveyor is located 54 meters from one entrance at an angle of 56°.

The surveyor is located 31 meters from one entrance at an angle of 13°.

Let the length of the tunnel = x meters

So, using the law of cosines, we get,

$x^2=54^2+31^2-2\times 54\times 31\times \cos 69$

i.e. $x^2=2916+961-3348\times 0.3584$

i.e. $x^2=3877-1199.9$

i.e. $x^2=2677.1$

i.e. x = 51.7 meters

Hence, the length of the tunnel is 51.7 meters

The length of a rectangle is x. The width of the rectangle is (x + 10). Write an expression for the area of the rectangle.

Fed [463]

Answer:

$A=x^2+10x$

Step-by-step explanation:

<u>Area of a Rectangle</u>

Given a rectangle of width W and length L, its area can be calculated with the formula:

A = WL

We are given the length of a rectangle is L=x and the width is W=x+10, thus the area is:

$A=x(x+10)$

Multiplying:

$\mathbf{A=x^2+10x}$
