Answer:

Step-by-step explanation:
First we need to set up an equation in order to find the value of x. We know that the sum of these angles are 180°

Now we can plug in our value for x into each of the angle's equations

The answer I got was 3 (may be wrong)
it has 24:6 ratio which is equal to 4 and 12/4 = 3
The common ratio r is 6, while the third term (ar²) is 24.
Nth term in a GP is given by the formula ar^n-1, thus the third term is ar²
ar²= 24
thus, a × 36 = 24
a =24/36
The ninth term is given by ar^8
= (24/36)× 6^8
= 1119744.
8+(16)/4 (divide 16 and 4 first, PEMDAS)
8+4 (add these two together)
12
