Answer: 114.37 ft
Step-by-step explanation:
If we model this situation as a right triangle, where the hypotenuse is the length of the ladder (
), the opposite leg is the height the ladder will reach
, and the adjacent leg is the distance between the base of the ladder and the building (
); we have two options:
1) Using trigonometric functions, since we are given the angle 
2) Using the Pithagorean Theorem
Any of the options will give a similiar result. So, let's choose the Pithagorean Theorem:


Isolating
:

Adding to this height the extra height of
(since the base of the ladder is at this distance above the ground, perhaps held by a firefighter truck):
This is the height the ladder will reach
Answer:
8
Step-by-step explanation:
16 divided by 8 equals 2 then 24 divided by 8 equals 3 Answer: 8
In step 2, you are adding 35.10 and 84.60. You carry the 1 to the 1's place after you add up the tenths and the hundreds place.
