Given :
A building is of unknown height. At a distance of 400 feet away from the building .
An observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º .
To Find :
How far is the poster from the roof of the building .
Solution :
Height is given by :
( Here , 
is angle of elevation )
So , height of tower :
For height of poster :
Therefore , distance of poster from the roof of the building is :
Hence , this is the required solution .
To answer this question, you need to understand how to change the description into an equation. Let say that Herbert's container volume is H and Betty's container is B. Then, from the problem you can get this equation:
1. B= 200 (Betty's container hold 200 milli liters)
2. H= 7/8 B (Herbert's container hold 7/8 as much juice)
If you put the 1st equation into the 2nd, you will get:
H=7/8 (200)= 175
Then the two containers will hold
H+B= 200 + 175= 375milli liters
Let's solve your equation step-by-step.
-9 ÷ 3 + b = -1
Step 1: Simplify both sides of the equation.
<u>−9</u>
3
+b=−1
−3+b=−1
b−3=−1
Step 2: Add 3 to both sides.
b−3+3=−1+3
b=2
Answer:
b=2
