HhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhGiven:

trap door = 130 square feet.

1st item: 6ft 5in wide & 8ft 9in long

⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in

⇒ 77inches by 105 inches

⇒ 8,085 square inches

2nd item: 13ft 4in wide & 7ft 8in long

⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in

⇒ 160 inches by 92 inches

⇒ 14,720 square inches

3rd item: 5ft 6in wide & 12ft 4in long

⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in

⇒ 66 inches by 148 inches

⇒ 9,768 square inches

130 square feet convert to square inches.

130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in

18,720 sq. in / 160 inches = 117 inches

Length = 160 inches ; Width = 117 inches

Perimeter = 2(160 + 117)

P = 2(277)

P = 554 inches

P = 2(277)

P = 554 inches

Well u know the area is 35 in^2 and the length is 7in. Let x = width

7x = 35

x = 35/7

Perimeter = 7(2) + 2(35/7) --> 14 + 70/7 --> 14 + 10 = 24

7x = 35

x = 35/7

Perimeter = 7(2) + 2(35/7) --> 14 + 70/7 --> 14 + 10 = 24

It's a lot to take in, isn't it ? I started off by confirming the formula a=lb

a=lb

65= (x×2)-3×x

l=(x×2)-3

b=x

a=65

Now I tried plugging in random values. Eventually I came up with this ;

65= (6.5×2)-3×6.5

65= 13-3×6.5

65 = 10×6.5

65=65

Length = 10feet

Width = 6.5feet

a=lb

65= (x×2)-3×x

l=(x×2)-3

b=x

a=65

Now I tried plugging in random values. Eventually I came up with this ;

65= (6.5×2)-3×6.5

65= 13-3×6.5

65 = 10×6.5

65=65

Length = 10feet

Width = 6.5feet

**Answer with explanation:**

Two Triangles are Congruent by following Geometrical Axioms

1. SAS

2.SSS

3. AAS

4. ASA

1. In Δ DEF and Δ P QR

PQ=DE

∠DEF=∠PQR→→Each being 90°

EF=QR

Δ DEF ≅ Δ P QR→→[SAS Congruency]

2. As in Image 2, only one angle is common

we can't say that triangles are congruent.

3. In ΔT UV and Δ W X Y

WX=TU

UV=XY

TV=WY

∠TUV=∠WXY

∠UTV=∠XWY

ΔT UV ≅ΔW X Y→→[By SAS or AAS or SSS]

4.In ΔABC and ΔFGH

∠A=∠F=83°

we can't say that triangles are congruent,as neither the other two angles nor the other two sides are equal.

5. None of the sides nor of the angles are equal .So the triangles are not congruent.

**→→So, Image 1, Image 3, are congruent Polygons. **

QUESTION POSTED AT 29/03/2020 - 04:32 PM

The side lengths of the two figures can be calculated with the distance formula:

√ (x1 - x2)² + (y1 - y2)²

AB = √13

BC = √13

CD = √13

DA = √13

A'B' = √13

B'C' = √13

C'D' = √13

D'A' = √13

They are all the same lengths. This supports an argument claiming that they are congruent because if the sides are congruent, then the two polygons are congruent.

Something else that must be true to say that two polygons are congruent is that the angles have equal measures.

*Hope this helps! :)*

QUESTION POSTED AT 28/03/2020 - 12:58 PM

In a right triangle, the hypotenuse is always the longest side. Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides. For the first "triangle" above: does ? Let's check. 196 = 25 + 16 so does 196 = 41? Obviously not. So that is not a right triangle. Let's check the second one the same way. Does ? 25 = 9 + 16. Does 25 = 25? Of course it does! So 1 is not a right triangle, but 2 is!

**The length of the longest metal rod that can be sent is 12 inches.**

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

=

Here, x is 7 inches.

So, Diagonal is =

= inches.

Rounding this to nearest whole number we get 12.

Space in the box = volume

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

Since we are given 2 sides and 2 angles, we can use the Side Angle Side (SAS) method. The area of a triangle is given by the formula:

Area = absinC/2; where a and b are adjacent sides and C is the angle between a and b.

Area = 5*8*sin31°/2 = 10.3 square units.

Area = absinC/2; where a and b are adjacent sides and C is the angle between a and b.

There is a mistake in your writing

:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

AB/AC = BE/CD.

We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22

Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8

2) y=0

3) x=3

4) 2y + (3*3y) = -15
