Answer:

D, 225

Step-by-step explanation:

Because this equation already has a1, it's useless to test with that, so instead solve for a2.

You would have a2 - 5a1, which would get you a2 = 5(9) because we already know what a1 is, which is 9. a2 = 45

Now we have a2, which is 45, so now we solve for a3

We would have a3 = 5a2 = a3 = 5(45) which is 225 which is a3

Answer Question QUICKILY please

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°.
