You must order a new rope for the flagpole, to do this you must first find the height of the pole. You observe that the pile casts a shadow 22 meters long on the ground. The angle of the elevation of the sun is 40 degrees. How tall is the pole?

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 answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
