Answer:
tn = 8n -7
Step-by-step explanation:
given : t2=9, t4=25
the formula is:
tn = t1 + (n-1) d
gonna find d first:
d = (25-9) /(4-2) = 16/2 = 8
and find tn1:
t1 = 9-8 = 1
so, tn = 1 + (n-1) (8) = 1 +8n -8
tn = 8n -7
Answer:
That is an octagon (eight sides).
Interior Angle Total = 1,080
EACH interior angle = 180 - (360 / 8) = 135
n + 161 + (n -12) +(n + 30) + n + 134 + (n+16) + 126 = 1,080
5n + 455 = 1,080
5n = 625
n = 78.125
Step-by-step explanation:
the diamiter is 125 meters because
