Answer:
Step-by-step explanation:
168.43%
(1/2)(n-4)-3=3-(2n+3)
n = 2
but if it is
(n-4)-3=3-(2n+3)
n = 7/3
the radius: r^2 = 81
r =9
c = 2*pi*r
= 2 * pi * 9
= 18 *pi
Answer: 18*pi or approximately 56.62
Step-by-step explanation:for the triangle GIF, angle g = 80
angle f = 42 since angle FBA = 138
so angle i = 180 - 42 - 80
= 58
