Answer:
12/5 gallons/minute, or 2 2/5 gallons/minute
Step-by-step explanation:
Find the unit rate with time as the independent variable:
2 gallons
---------------- = 12 gallons / 5 minutes = 12/5 gallons/minute
5/6 minute

See the attached figure to better understand the problem
we know that
in the triangle ABC
tan(alfa/2)=AC/BC----> 5/3
so
(alfa/2)=arctan (5/3)---------> 59.0362°
alfa=2*59.0362--------> alfa=118.07°
alfa+beta=180°----------> because are supplementary angles
beta=180-118.07-------> beta=61.93°
the answer is
the angles are
alfa=118.07°
beta=61.93°
