The ratio is common, so you could write:
a1 * r^4 = a^5 (you do r^4 because there are 4 times you need to multiply by the ratio to get from a1 to a5)
Plug in the values:
3 * r^4 = 48
Divide by 3:
r^4 = 16
Take the fourth root of both sides:
r = 2
The common ratio is 2.

Answer:
<h2>x=52</h2>
Basic fact:
<em>angles in a point add up to 360</em>
Step-by-step explanation:
20+165+33+90(that is the right angle)+x=360
20+165+33+90=308
308+x=360
-308
x=52
