Answer:
95⁰
Step-by-step explanation:
next time you want to figure this out, here's how
- they are supplementary angles, so you just subtract 45⁰ from 180⁰
180-45=95
so, you would get the answer 95⁰
for next time, you might not have as much information as you do in this equation so be careful
hope this helps!

Answer:
243.01.
Step-by-step explanation:
The first term (a) = 324.
The common ratio (r) = -108/324 = -1/3.
So sum of 9 terms is:
S(9) = 324 * (1 - (-1/3)^9) / ( 1 - (-1/3)
= 324 ( 1 - (-0.00005076)) / 4/3
= 324 * 1.00005076 / 1.33333
= 243.012.
