Answer:

360 degrees

Step-by-step explanation:

A rotation symmetry angle is an angle with which a figure is rotated and still looks the same as if it wasn't turned.

For example, a square has a minimum angle of rotational symmetry of 90 degrees, because if you turn it by 90 degrees, it still looks exactly the same way.

This rotational symmetry is mostly used with regular shapes.

This quadrilateral is not a regular shape, and there's only one way to have it look exactly like it is now... and it's to do a full turn, of 360 degrees.

The answer is 76.

Step-by-step explanation:

≅ means to be equal to.

☆Angle DGE ≅ EGF.

Therefore, 3x + 8 = 5x - 12

☆Let's solve that equation.

$3x + 8 = 5x - 12 \\ \frac{ - 5x \: \: \: \: \: \: \: = - 5x \: \: \: \: \: \: \: \: }{ - 2x + 8 = - 12} \\ \frac{ \: \: \: \: \: \: \: \: - 8 = - 8}{ \frac{ - 2x}{ - 2} = \frac{ - 20}{ - 2} } \\ x = 10$

We found the value of x which is 10.

☆Let's Now plug in.

$DGE \\ 3x + 8 \\ 3(10) + 8 \\ 30 + 8 \\ 38$

and the other:

$EGF \\ 5x - 12 \\ 5(10) - 12 \\ 50 - 12 \\ 38$

☆They asked for what the angle of DGF measured. So we would have to add both sides

$38 + 38 = 76$

☆The answer is 76

Find the surface area of a square prism with a side measure of 15

Phoenix [80]

Since the length is 15, and the width would be 15, you need to first do 15 x 15.

15 x 15 = 225

Multiply the 6 faces.

225x6

Your final answer would be 1,350.

a company charges a $75 setup fee plus $5.25 per shirt to silkscreen a desing on specialty t-shirts. write an equation which giv

Mila [183]

The equation for this is quite simple. Take note x is the amount of shirts sold and 5.25 is the cost for each one to which they add a 75 setup fee.

So the equation will be

75+(5.25x)=
