Item 9 A surveyor is standing 118 feet from the base of the Washington Monument. The surveyor measures the angle of elevation from the ground to the top of the monument to be 78∘. Find the height h of the Washington Monument to the nearest foot. Item 9 A surveyor is standing 118 feet from the base of the Washington Monument.

555 ft

Step-by-step explanation:

aee the attached figure to better understand the problem

we know that

In the right triangle ABC

----> by TOA (oppsoite side divided by the adjacent side)

substitute the given values

solve for h

answer: the answer is 23

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
