The accompanying diagram shows a 24-foot ladder leaning against a building. A steel brace extends
from the ladder to the point where the building
meets the ground. The brace forms a right angle
with the ladder. If the steel brace is connected to
the ladder at a point that is 10 feet from the foot of the ladder, which
equation can be used to find the length, x, of the steel brace?

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 :
