two sides of this regular octagon are extended to form a right-angled triangle. using given information, find the measure of angle k.
a. 155°
b. 145°
c. 135°
d. 125°

b if for most of the graph

d if y intercept

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
