Answer:
This is the concept of geometric series. We are required to find the recursive formula for year n. Here we will use the formula;
nth=ar^(n-1)
where;
a=first term
r=common ratio
n=nth term
Thus
a=8.50
r=(8.85)/(8.50)=1.0412
thus the formula will be:
nth=8.50(1.0412)^n
well, we know the "sum" of both angles is 90°, notice the rectangle in the corner, so we can say that the angles are simply complementary angles, thus

idk that's what Alexa said, sorry if it's wrong
Answer:
x = 3
Step-by-step explanation:
9x - 5 = 22
Add 5 to both sides
9x = 27
Divide both sides by 9
x = 3
