To find the number of seats, let's do it using multiplication!
First, to see how many seats are in one big section of the theatre, multiply 7 groups of seats by 25 seats:
7 x 25 = 175
Now, knowing this, multiply 175 by 4 to get the total number of seats in the theater!
175 x 4 = 700
Therefore, there are 700 seats in the theatre.
Hope this helps!
A conjugate angle is 360°, 360-70=290!
