x = 138°

Step-by-step explanation:

So if we know that all the angles added up are 180 degrees, we would do 180° - 70° - 68° to get the missing angle in the triangle which is 42 degrees. Then, we would do 180° - 42° to get x because a straight line is 180 degrees. Therefore, the answer is x = 138°

where is the diagram? shown below where? ?

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
