Answer:

1,2,3 and 6 are similar triangles by AA similarity

Step-by-step explanation:

1) ∠DEC ≅ ∠FEG     {Vertically opposite angles}

DC //  GF

∠ECD ≅ ∠EGF     {Alternate interior angles}

∠EDC ≅ ∠EFG     {Alternate interior angles}

ΔDEC & ΔFEG are similar triangles by AA similarity

2)MN // QP

∠LQP ≅ ∠QMN   {Corresponding angles }

∠LPQ ≅ ∠PNM   {Corresponding angles}

ΔLQP & ΔLMN are similar triangles by AA similarity

3) In ΔSYE ,

∠S = 180 - 90 - 39

∠S = 51°

In ΔCHW,

∠H = 180 - 51 - 90

∠H = 39

ΔSYE and ΔCHW

∠S ≅ ∠W = 51°

∠Y ≅ ∠C = 90°

∠E ≅∠H = 39°

ΔSYE & ΔWCH are similar triangles by AA similarity

6) ∠P ≅ ∠Z      {Given}

∠PXQ ≅∠ZXY  {Vertically opposite angles}

ΔPXQ & ΔZXY are similar triangles by AA similarity

4. A triangle with base (2x+2) and height (x-2) is cut out of a rectangular sheet of paper that is (3x+4) by (2x+3) what is the
juin [17]
So what we do is
area that remains=total area-triangle area that was cut out


we need to find 2 things
total area
triangle area

total area=rectange=base times height
area=(3x+4) times (2x+3)
FOIL or distribute
6x^2+8x+9x+12=6x^2+17x+12

triangle area=1/2 times base times height
triangle area=1/2 times (2x+2) times (x-2)=
(x+2) times (x-2)=x^2+2x-2x-4=x^2-4


so
total area=6x^2+17x+12
triangle area=x^2-4

subtract
area that remains=total area-triangle area that was cut out
area that remains=6x^2+17x+12-(x^2-4)=
6x^2+17x+12-x^2+4=
6x^2-x^2+17x+12+4=
5x^2+17x+16


area that remains is 5x^2+17x+16

jok3333 [9.3K]

Answer:

w=3

Step-by-step explanation:

3w= 9

divide 3 on both sides

3/3 = 9/3

3/3 cancels out

9/3 = 3

Find the measure of x, y, and z. Enter your answer as a number, rounded to the nearest tenth if needed.
weeeeeb [17]

Answer:

x = 6.

y = 6.7.

z = 13.4.

Step-by-step explanation:

The 2 triangles contained in the biggest one are similar, so:

x/12 = 3/x

x^2 = 36

x = 6.

Applying the Pythagoras theorem:

z^2 = 6^2 + 12^2

z^2 = 36 + 144 = 180

z = 13.4.

y^2 = x^2 + 3^2

= 36 + 9

= 45

y = 6.7

V = lwh/3 (solve for h)
victus00 [196]

Answer:

\displaystyle V = \frac{lwh}{3} \rightarrow h = \frac{3V}{lw}

General Formulas and Concepts:

<u>Pre-Algebra</u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle V = \frac{lwh}{3}<em />

<em />

<u>Step 2: Solve for </u><em><u>h</u></em>

  1. [Multiplication Property of Equality] Multiply 3 on both sides:                     \displaystyle V = \frac{lwh}{3} \rightarro 3V = lwh
  2. [Division Property of Equality] Divide lw on both sides:                               \displaystyle V = \frac{lwh}{3} \rightarrow h = \frac{3V}{lw}
