The amount of fabric in inches Felicia need to make the actual shape for the comforter is 660 in²

<h3>What is a trapezoid?</h3>

It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.

We have a trapezoid in the picture shown with dimensions.

We know the area of the trapezoid is given by:

\rm A = \dfrac{a+b}{2} \times h

Here a = 15 cm, b = 22 cm and h = 11 cm

\rm A = \dfrac{15+22}{2} \times 11

A = 203.5 square cm

To make the square from the trapezoid, Felicia needs to cut two triangles from the both end, as shown in the figure.

The height of the triangle = 11 cm

And base length = (22-15)/2 = 3.5 cm

The area of the triangle = (11×3.5)/2 = 19.25 square cm

Area of the two triangles = 2×19.25 = 38.5 square cm

Now the amount of fabric  =  203.5 -  38.5 = 165 square cm

As the scale is given 1 cm = 2 in

1 cm ² = 4 in²

So, the amount of fabric in inches = 165×4 = 660 in²

Thus, the amount of fabric in inches Felicia need to make the actual shape for the comforter is 660 in²

The sum of two numbers is 53 and the difference is 11. What are the numbers?
vaieri [72.5K]
Let assume that the the two numbers are X and Y and that X is the large number.
According to the question, 
X + Y = 53 .................. Equation 1
then,  X = 11 + Y........... Equation 2
Substitute equation 2 into equation 1.
[11 + Y] + Y = 53
11 + 2Y = 53
2Y = 53 - 11 = 42
2Y = 42
Y = 42 / 2 = 21,
Therefore, Y = 21 [Small number].
According to equation 1, 
X +Y = 53
X + 21 = 53
X = 53 - 21 = 32.
Therefore, X = 32 [Big number].

Point D is in the interior of ZABC, m ABC = 10x - 7, m_ABD = 6x + 5, and m DBC = 36. What is m ABD?
mestny [16]

Answer:

<h3>77</h3>

Step-by-step explanation:

If Point D is in the interior of <ABC, then <ABD+<BDC = <ABC

Given

<ABC = 10x - 7,

<ABD = 6x + 5

<DBC = 36

Substituting the given parameters into the formula above;

ABD+<DBC = <ABC

6x + 5+ 36 = 10x-7

6x+41 = 10x-7

collect like terms

6x-10x = -7-41

-4x = -48

divide both sides by -4

-4x/-4 = -48/-4

x = 12

To get <ABD, we will substitute x = 12 into the expression <ABD = 6x + 5

<ABD = 6(12)+5

<ABD = 72+5

<ABD =77

Hence the value of <ABD is 77
