The owner of an office building is expanding the length and width of a parking lot by the same amount. The lot currently measure
nasty-shy [4]

Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000

So if increase in length = x we have

(x + 120)(x + 80) = 14,000

x^2 + 200x + 9600 - 14000 = 0

x^2 + 200x - 4400 = 0

x = 20 feet answer

Find the value of x.<br> 108°<br> 40°<br> x = [ ? 1°
tensa zangetsu [6.8K]

Answer:

x = 28°

Step-by-step explanation:

Take angle on a straight line which is equal to 180°

180° =(108 + 44 + x)°

180° = 152° + x°

180° - 152° = x°

28° = x

Identify the area of the polygon with vertices t(6,5), a(8,−1), s(4,−2), and k(−1,4).
densk [106]

Answer:

  36.5 square units

Step-by-step explanation:

There are a number of ways to compute the area of a polygon from the coordinates of its vertices. There are algebraic formulas, geometric methods involving decomposing the figure, and an interesting method described by Pick's theorem.

__

<h3>Geometry</h3>

The figure can be enclosed by a rectangle that is 7 units high by 9 units wide. The actual figure is obtained by removing the triangular corners of this rectangle. The areas of those are given by the triangle area formula ...

  A = 1/2bh

Working clockwise from lower left, the triangle base (horizontal) and height (vertical) dimensions are 5×6, 7×1, 2×6, 4×1. That means the area of the triangles is ...

  A = 1/2(5×6 +7×1 +2×6 +4×1) = 1/2(30 +7 +12 +4) = 1/2(53) = 26.5

The area of the bounding rectangle is ...

  A = bh = 9×7 = 63

So, the area of the figure is the difference ...

  A = 63 -26.5 = 36.5 . . . square units

__

The other methods of finding the area have been added as attachments.

SOLVE FOR X PLEASE HELP LEAVE IN FRACTION AND DECIMAL​
enyata [817]

Answer:

x = \frac{22}{3}

Step-by-step explanation:

Since both CB and ED intersect AD perpendicularly, we can say they are parallel and that ΔACB is similar to ΔAED from Thales intercept theorem. Now, we can set up a proportion from the definition of similar triangles:

\frac{AB}{AD}  = \frac{BC}{DE}

We can say that AD = AB + BD(segment addition postulate) and substitute to get AD = 11. Now we can plug in the numbers we have to the proportion:

\frac{6}{11} =\frac{4}{x}

We can cross-multiply to get:

6x = 44

and divide by 6 to get

x = \frac{22}{3}
