All you really have to do is find the measure of angle T - if T=R then when you find the measure of T then it will also = R
Answer:
4 times
Step-by-step explanation:
The left side, because you only need to move one thing, and you don't need to subtract after that. (you can add, much more easier)
hope this helps
A(n)=ar^(n-1) so
100=4r^9
25=r^9
ln25=9lnr
ln25/9=lnr
r=e^(ln25/9)
a(n)=4e^((n-1)(ln25/9) if you wanted an approximation...
a(n)=4(1.43^(n-1))
X=4
4(4) + 1 =
16 + 1= 17
the answer is 17
