Quadrilateral PAID is a rectangle whose diagonals have the endpoints P(-3, -2)I(4, -7) and A(4, -2)D(-3, -7). Find the diagonals
BARSIC [14]

Answer:

(0.5,-4.5)

Step-by-step explanation:

The given rectangle has diagonals have the endpoints P(-3, -2) ,I(4, -7) and A(4, -2) ,D(-3, -7)

The diagonals of the rectangle bisect each other so we use the midpoint formula to find their point of intersection.

The midpoint formula is;

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

We use any pair of endpoints of the diagonals to find the point of intersection.

Using A(4, -2) ,D(-3, -7)

(\frac{4+-3}{2},\frac{-2+-7}{2})

(\frac{1}{2},\frac{-9}{2})

or

(0.5,-4.5)

See the attached figure to understand the problem

we know that
tan 42°=1950/BO---------> BO=1950/tan 42°-------> BO=2165.69 ft

tan 39.5°=1950/AO---------> AO=1950/tan 39.5°-------> AO=2365.54 ft

AB=AO-BO--------> AB=2365.54 ft-2165.69 ft-------> AB=199.85 ft

the answer is
The runners are 199.85 feet apart

You decide to install a fence around your property and want to know how many linear feet you have to determine the cost of the f
Debora [2.8K]

Answer:

The answer to this question is

The linear footage of the perimeter fence = 1250 feet

Step-by-step explanation:

To find the linear footage requires the footage measurement with a measuring tape. The linear footage indicates the length of the fence required to surround the property from which the cost of fencing the property can be estimated by multiplying the linear footage of the perimeter fence by the cost to build a unit length of fence

The linear footage of the perimeter fence to surround the property can be found by the equation for solving the perimeter of a rectangle which is

Perimeter = 2× (length+breadth) = 2×(475+150) = 2×625 = 1250 foot

The linear footage of the perimeter fence = 1250 foot
