What is the value of x in the triangle below

40 degrees

Step-by-step explanation:

The three angles in a triangle add up to 180 degrees. Therefore, if you know the measurements of two angles, you can figure out the measurement of the other angle by doing this:

180 degrees - 65 degrees - 75 degrees = 40 degrees

If you want to check your answer, 65 degrees + 75 degrees + 40 degrees = 180 degrees.

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

192/15 = 12.8.

12.8

step-by-step explanation:

192/15 is 12.8.

however, it says to round to the nearest foot, which would equal 13.
