Three sides of a triangle measure 9,9 and 15. What is the measure of the angle opposite the side which measures 15 rounded to the nearest degree? Do not write units.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

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
