Answer:

Explanation:

Work out the equation:

1st row is 11 seat and the seat after it will be 6 more and 6 more after the second row and so on. This can be written:

6(x - 1) + 11 =

Where x determine the number of row.

Ex: if x = 1 thus, 6(0) + 11 = 11 seat which is the first row.

Find the number of seats in row 18:

6(18 - 1) + 11
6(17) + 11
= 102 + 11
= 113 seats

I’m confused on this one
otez555 [7]

Well a circle has 360 degrees and this question wants the degree of counter-clockwise.

I think first we subtract 69 from 360, since that is the rotation clockwise, to get the angle of rotation.

360 - 69 is 291 degrees
