Question 2: Use the diagram below to answer parts a, b, and c. a. If angle 1 is congruent to angle 2, what two lines must be parallel?
b. If PARD is a parallelogram, then segment PO must be congruent to
what other segment?
c. If PARD is a rhombus, then what kind of angle is angle POD?

a. PD and AR

b. OR

c. a right angle

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.

the rate of change is 25
