Step-by-step Solution for Part-a:
<u>We know that:</u>
- Row-1: 20 seats
- Row-2: 20 + 11
- Row-x: 20 + (11x - 11)
Since the number of rows in rows x is 20 + (11x - 11), the formula to calculate the number of seats in each row is 20 + (11x - 11).

Step-by-step Solution for Part-b:
<u>We know that:</u>
- y rows = 174 seats
- Obtained rule from part-a: 20 + (11y - 11)
<u>Solution:</u>
- 20 + (11y - 11) = 174 rows
- => 20 + 11y - 11 = 174 rows
- => 9 + 11y = 174 rows
- => 11y = 174 - 9 rows
- => 11y = 165
- => y = 165/11
- => y = 15
Hence, the row which has 174 seats is row 15.

Answer:
AD = 6.76 inches
Step-by-step explanation:
Taking the triangle ABC:
tan 45° = AB/BC
1 = AB/BC
AB = BC = 16 in
Taking the triangle DBC:
tan 30° = DB/BC
DB = BC * tan 30°
DB = 16 * tan 30°
DB = 9.24 in
Given that AD + DB = AB, then
AD = AB - DB
AD = 16 - 9.24 = 6.76 inches
Let the people initially on the train be 'x'.
19 people got off the train --> x - 19
17 people got on the train --> x - 19 + 17
Remaining people on the train = 63
Therefore, x - 19 + 17 = 63
x - 2 = 63
x = 63 + 2
x = 65
Verification:
65 - 19 + 17 = 63
65 - 2 = 63
63 = 63
