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°.
