Drag each figure to show if it is similar to the figure shown or why it is not similar
Margarita [4]

Answer:

Step-by-step explanation:

The given figure is a rectangle having length = 9 yd and width = 3 yd

Now we will check each figure

Figure one- rectangle with length = 18 yd and width = 9 yd

For similarity of both rectangles ratio of length should be equal to ratio of widths.

\frac{3}{9}\neq\frac{9}{18}

So rectangles are not similar.

Figure 2- rectangle with length = 3 yd and width = 6 yd

\frac{9}{3}\neq \frac{3}{6}

So figures are not similar.

Figure 3 - rectangle with length = 3 yd and width = 1 yd

\frac{9}{3}=\frac{3}{1}

Therefore, figures are similar.

Figure 4 -rectangle with length = 8 yd and width = 2 yd

\frac{3}{2}\neq \frac{9}{8}

So given rectangles are not similar.

Figure 5 - rectangle with length = 18 yd and width = 6 yd

\frac{9}{18}=\frac{3}{6}

So rectangles are similar.

Figure 6 - trapezoid with larger base = 18 yd and height = 6 yd

Since shapes of the given figures are not same so they are not similar.

Find the value of x. Diagram not to scale
lara31 [8.8K]
We first need to find the sum of the interior angles in a pentagon, which you do by doing (5 - 2) × 180, which equals 3 × 180 = 540°. Now you know that all of the angles inside the shape must add up to 540, so you can make an equation:
90 + 112 + 2x + 148 + 2x + 10 = 540
360 + 4x = 540
- 360
4x = 180
÷ 4
x = 45

I hope this helps!

Omega House Family restaurant is midway between Forsyth Tech Community College
Veseljchak [2.6K]

The coordinates of Omega house is (3/2, 1)

Data;

  • Forsyth Tech = (7,-5)
  • Stadium = (-4, 3)

<h3>Midpoint of a Line</h3>

To find the coordinates of Omega house, we can use the formula of midpoint of a line since Omega house falls between Forsyth Tech and Stadium

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

We can substitute the values and solve for both x and y coordinates.

x = \frac{x_1+x_2}{2} \\x = \frac{7 + (-4)}{2} = \frac{3}{2}

The value of the y-coordinate is

y = \frac{-5+ 3}{2} = 1

The coordinates of Omega house is (3/2, 1)
