Aladder that is 32 feet long leans against a building. the angle of elevation of the ladder is 70 degrees. to the nearest tenth of a foot how high off the ground is the top of the ladder?

The top of the ladder is 30 feet high off the ground.

Step-by-step explanation:

Since we have given that

Length of ladder AC = 32 feet

Angle of elevation of the ladder = 70°

We need to find the height of top of the ladder high off the ground i.e. AB.

Consider, Δ ABC,

Hence, the top of the ladder is 30 feet high off the ground.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

the answer is the third / last answer
