Because the two angles on the right add to 180 degrees, we can create this system:

We can also prove that

, which, when solved, shows that

.
When plugged in to the original equation, we find that y = 105 degrees.
The solution to the problem is as follows:
Just plug in the numbers and follow the pattern.
a0 = 1
a1 = 2*1 + 2 = 4
a2 = 2*4 +2 = 10
<span>a3 = 2*10 +2 = 22

I hope my answer has come to your help. God bless and have a nice day ahead!
Ya
compound interest
A=P(1+r)^t
A=amount final
P=principal
r=rate in decimal
t=time in yers
so
interest is 9.5% or 0.095
principal is 10000
time is 3 years
A=10000(1+0.095)^3
A=10000(1.095)^3
A=13129.323
rounded
he owes $13129.32
