Answer Question QUICKILY please

Find the measure of the numbered angle.
Select one:
a. 92
b. 95
c. 94
d. 90

Answer 1

In a circle, the internal vertical angles have a formula of
`(a + b)/(2)`

In this case, the formula would be:
`(4x + 2x)/(2) = (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 * 30 = 90`

So, angle 7 is 90°.
