Answer:
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.
Explanation:
Let a be the capacity of old tank and b be the capacity of new tank.
A company added a new oil tank that holds 350 barrels of oil more than its old oil tank.
So we have b - a = 350 ----------------------equation 1
Together they hold 3650 barrels of oil
a + b = 3650 ----------------------equation 2
equation 1 + equation 2
2b = 3650 + 350 = 4000
b = 2000 barrels.
Substituting in equation 1
2000 - a = 350
a = 1650 barrels.
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.

idk but trump 2020
Step-by-step explanation:
Really, we don't need to use that much math--we can use logic instead. Since the two congruent sides must be longer than 30in, the total has to be greater than 60in (the longest side plus the congruent sides.) So for our answer, we want the smallest total that is above sixty, which in this case is 72.44in.
Hope I helped, and let me know if you have any questions :) I can explain the real math if you want, it was just unnecessary here.
