They both are acute angles
Either or can be used with any triangle...I personally find the law of sines is often more compact as in this case we can just say;
(sin115)/18=(sin40)/c (with no need for b or B as would be needed with the law of cosines...)
c=18(sin40)/(sin115)
c≈12.77
First multiply the 3 lengths given to find the volume:
5•2.2•0.8=8.8
Then multiply again:
7.48•8.8=65.824
Answer: 65.824 gallons

Answer: °F/ft (Same as °F·ft⁻¹)
EXPLANATION
Rate at which
temperature changes as the altitude increases
= Change in temperature/Change in Altitude
To find the appropriate units for Anoop’s purpose:
Change in temperature has the same units as Temperature, F (Fahrenheit)
Change in Altitude has the same units as Altitude, ft (Feet)
Therefore, The appropriate unit for Change in temperature/Change
in Altitude is °F/ft (Same as °F·ft⁻¹)
Answer:
20
Step-by-step explanation:
19,20,21
the second even number is 20
19+21=40
