Answer:
Slope: -3/2
With the question, we can determine that the slope with two points: (0,13.5) and (9,0). To calculate use the equation
and get 
This slope means that the water is decreasing at a rate of 3/2 gallons per minute.

- Base = 2 9/10 km
- Height = 4 6/7 km







<em>Thus, The area of the triangle is 3.08 kilometers...~</em>
Answer:
9
Step-by-step explanation:
90+81+mising angle=180, missing angle is 9
90 because how many more means to subtract so u subtract 150 from 60 and you will get 60.
The slope is 2/2 ; rise over run
