Answer:

-9

Step-by-step explanation:

(x-2) is 3 more than (x-5), because -2 is 3 more than -5.

3 more than -12 is -9.

_____

If you like, you can solve for x.

... x -5 = -12

... x = -7 . . . . . add 5

Now find the value of x-2

... x -2 = -7 -2 = -9

3. A recent tornado in a small town in Southwest New York destroyed and damaged
tester [92]

Answer:

\text{Area of the Land}=62906.91 ft^2

Step-by-step explanation:

To determine the area of the land, we first determine the length of the base.

Since it is a isosceles trapezoid,

Length of the base =(228+2x)ft where x is the base of the triangle.

In the Right Triangle,

Perpendicular Height =209 ft

Hypotenuse =221.38 ft

Using <u>Pythagoras Theorem:</u>

Hypotenuse^2=Opposite^2+Adjacent^2\\221.38^2=209^2+x^2\\x^2=221.38^2-209^2\\x^2=5328.1044\\x=\sqrt{5328.1044} \\x=72.99\: ft

Therefore, the length of the isosceles' trapezoid base

=228+2(72.99)=373.98ft

Area of a trapezoid

A=\frac{1}{2}(a+b)h\\$Where a and b are the parallel sides\\h=Perpendicular Height

a=228ft, b=373.98ft, h=209ft

Area=\frac{1}{2}(228+373.98)209\\=\frac{1}{2}*601.98*209\\$Area of the Land=62906.91 ft^2
