Answer:
Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°.
Step-by-step explanation:
A=35+5t, b=100-8t, a=b when:
35+5t=100-8t subtract 35 from both sides
5t=65-8t add 8t to both sides
13t=65 divide both sides by 13
t=5 minutes
a=35+5(5)=60 gallons
So the tanks have an equal volume of 60 gallons after five minutes.
