The length of string used to decorate the ceiling = 40.5 meters.

According to the statement

we have given that the hotel staff is decorating the lobby by placing one row of string lights along the outer edge of the rectangular ceiling.

And the coordinates of rectangular ceiling is A(5,16), B(17,10), C(14,4), D(2,10).

And we have to find the total length for string is used to decorate the rectangular ceiling.

We know that the Total length of string = Area of the rectangular ceiling.

And area of rectangular ceiling = L*B

So, Length of rectangular ceiling = A+B

Length of rectangular ceiling = (17-5) + (16-10)

Length of rectangular ceiling = (12+6)/2

Length of rectangular ceiling = 9.

So,

Breadth of rectangular ceiling = B+C

Breadth of rectangular ceiling = (17-14)+(10-4)

Breadth of rectangular ceiling = (3+6) /2

Breadth of rectangular ceiling = 4.5

So, the length of string used = 4.5*9

the length of string used = 40.5 meters.

The length of string used to decorate the ceiling = 40.5 meters.

Answer and Step-by-step explanation:

We are given a triangle, a quadrilateral inside a triangle. and exterior angles of the triangle at linear bisectors.

We can figure out the interior angles of the shape to find a by using the linear bisector theorem, in which a line separated by another line will have two angles that will add to 180 degrees.

For the bisected line with the angle of 60 degrees, the other angle will have to equal 120. We know this by taking 60 from 180.

The perpendicularly bisected line will always have 90 degrees for the angles, so the interior angle will be 90 degrees.

For the bisected line with the angle of 80 degrees, the other angle will have to equal 100. We know this by taking 80 from 180.

Now, we have angles to determine a.

Quadrilaterals consist of 4 interior angles, which, when added together, equals 360 degrees.

360 - 90 - 100 - 120 = a

260 - 90 - 120 = a

140 - 90 = 50 = a

So, angle a is equal to 50 degrees.

y =  1/4(x - 2)^2 - 2

The formula for the focus of the parabola y = a(x - h)^2 + k is (h, k+1/4a)

Step-by-step explanation:

The standard form of the given equation is: y = -3(x-6)²+35.

In mathematics, the most typical way to represent a specific element is called standard form.

A standard form is a way to express a particular mathematical idea, such as an equation, number, or expression, in prose that adheres to a set of criteria.

Given equation is: y = − 3x² + 36x - 73

In order to convert to the standard form,

y+73 = −3x² +36x

Subtract 108 from both the sides,

y+73-108 = −3x² +36x-108

y-35 = -3(x² -12x+36)

y-35 = -3(x-6)²

y = -3(x-6)²+35

The measure of angle GFD of the circumscribed circle is; A: 40°

From the figure, we can apply the arc angles summation formula to get;

Major angle ∠FED + Minor angle ∠FED = 360°

We are given that Major arc FD measures 280°. Thus;

280° + Minor angle ∠FED = 360°

Minor angle ∠FED = 360° - 280°

Minor angle ∠FED = 80°

Also, we know that;

∠FED + ∠FGD = 180°

Thus, putting ∠FED = 80° gives us;

80° + ∠FGD = 180°

Subtract 80° from both sides using subtraction property of equality to get;

∠FGD = 180° - 80°

∠FGD = 100°

Now, GF and GD are the tangents to the circle from the same point G. Thus, we can say that;

GD = GF

Therefore,

∠FDG = ∠GFD = x

(This is because ∠FDG and ∠GFD are the angles opposite to equal sides.

In triangle FGD, we have sum of interior angles = 180°

Therefore, we have the expression;

∠FDG + ∠FGD + ∠GFD = 180° (due to the fact that sum of angles in a triangle is equal to 180°)

x + 100° + x = 180°
