Distance from the building where the fireman is standing = 25 m due yo the west pointed angle of elevation of the ladder = 51 degrees You then aquire the length of the ladder equals...
x ThenCos 51 degree = 25/x0.6293
= 25/xx = 25/0.6293 = 39.72 meters≈40 meters from the above deduction, so the correct answer is D, because it is the closest, and that it is correct.
Answer:20
Step-by-step explanation:
1) You add (6+4) and should get 10

Do you understand?
Divide x by y and compare:
5/1 = 5
10/2 = 5
20/4 = 5
All 3 are the same number so yes the rate of change is constant.
