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
If u are looking for x its 4 because if y=2 then u substitue it for y and you get -x+2=-2. to get x by its self you have to subtract 2 from both sides and u end up with -x=-4 and u have to divide -x by -1 to get rid of the negative and u get x=4
1. Check the picture attached.
2. m(AOB)=2x as it is a central angle, intercepting the same arc (AB) as ACB.
3. AO=OB=1, as they are radii of the unit circle.
4. From the cosine theorem:
substituting the known values:
