Solve for Y please!!!

hodyreva [135]

From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60° <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64° <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8° <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°

Chloe is installing new windows in her house and needs to determine the amount of sealant she will need around the outside edge

Bingel [31]

Perimeter of window is 192 inches.

Step-by-step explanation:

We are given:

Area of rectangular window = 2160 inches square

Length of rectangular window = 60 inches

Required:

Perimeter of window=?

Formula to find Perimeter is:

$Perimeter=2(length+Width)$

We first find width of rectangular window by using formula of area:

$Area=Length*Width$

Putting values:

$Area=Length*Width\\2160=60*Width\\Width=\frac{2160}{60}\\Width=36\,\,inches$

So, width = 36 inches

Now finding perimeter:

$Perimeter=2(length+Width)\\Perimeter=2(60+36)\\Perimeter=2(96)\\Perimeter=192\,\,inches$

So, perimeter of window is 192 inches.

21. Is the histogram uniform, symmetric, or skewed? (1 point)<br> uniform<br> symmetric<br> skewed

lapo4ka [179]

Answer:

Symmetric

Step-by-step explanation:

The data is spread out symmetrically. It isn't uniform because the values aren't around each others values. It isn't skewed because the data isn't 'closer' to one side.

p → q represents the original conditional statement and the contrapositive of the original conditional statement. Then the correct options are A and E.

The missing options are given below.

<h3>What is dilation?</h3>

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.

There is no effect of dilation on the angle.

Doubling the dimensions of a rectangle increases the area by a factor of 4.

If p represents doubling the dimensions of a rectangle and q represents the area increasing by a factor of 4.

Then the true statement will be

Then the correct options are A and E.
