Can you anser number 9

Step-by-step explanation:

Equations

Let's call

x = measure of angle 1

y = measure of angle 2

The angles are supplementary, thus their sum is 180°:

x + y = 180        [1]

It's also known that one angle (x) is 7° more than twice the other (y), thus:

x = 7+ 2y        [2]

Substituting [2} in [1]:

7+ 2y + y = 180

Operating:

7+ 3y = 180

Subtracting 7:

3y = 180 - 7 = 173

Dividing by 3:

And:

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
