Answer:
≈ 32°
Step-by-step explanation:
Distance between buildings= 91 m
Elevation difference= 192 m- 136 m= 56 m
Right triangle ΔABC is formed by connecting 3 points, see attached
∠C is one to be calculated
tan C=AB/AC= 56/91
tan C= 0.62
∠C ≈ 32°
-------------------
<em>∠B = (90°-32°)= 58° in case I misread which angle to be found</em>
If both pipes are opened. Then the number of hours to fill up the tank fully is 100 hours.
The complete question is attached below.
<h3>What are ratio and proportion?</h3>A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
Let t be the filling time.
Then we have
Time is inversely proportional to rate of filling tank.
1/20 – 1/25 = 1/t
0.05 - 0.04 = 1/t
0.01 = 1/t
t = 1/0.01
t = 100 hours
