Answer:
x = 47°
Step-by-step explanation:
Since the two angles on a line add up to 180 degrees:
x = 180-133
x = 47°
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.
61.67$ because you round the 7 up to the nearest hundredth
