Lines l and m are parallel. Which of the following pairs of angles are alternate interior angles? ∠1 and ∠4 ∠2 and ∠3 ∠6 and ∠8

the following alternate pairs are 1 and 4 because it's a mirror

Step-by-step explanation:

angles 2 and 3

Step-by-step explanation:

The question is asking for alternate interior angles, meaning the angles must be between the two parrall lines, but on diffrent sides of the transversal. this leaves only 2 and 3.

a is the right answer

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
