In a circle, the internal vertical angles have a formula of $\frac{a + b}{2}$

In this case, the formula would be: $\frac{4x + 2x}{2} = \frac{6x}{2} = 3x$

We know that whole circle is 12x. And 12x is equal to 360°. When we put that into equation: $12x = 360$
$x = 30$

If x is 30°: $3x =3 \times 30 = 90$

So, angle 7 is 90°.

Answer:

(4,0)

Step-by-step explanation:

The object is first at (0,0)

It is reflected across line x=-2, this means you draw the mirror line at x=-2 and count 2 equal units backwards to get the image.The image will be at ; $y=0\\\\x=-2-2=-4\\\\\\=(-4,0)$

The image (-4,0) is then reflected on the y-axis

You know reflection on the y-axis, the y-coordinate remains the same but the x-coordinate is changed to its opposite sign.

Hence;

(- -4,0)= (4,0)

The image will move 8 units towards positive x-axis.This is the same as moving 4 units from the mirror line at (0,0) and land at (4,0)

14.4% of what number is 10.4

Helga [31]

First, convert "of" to x and put this info into an equation:

Let n represent the unknown number.

14.4 % x n= 10.4
n = 10.4 / 14.4%
n = 72.22222
n = ~72

Hope this helps!
