90 sides give us 90 angles
sum of all inside angels is (n-2) * 180 deg. where n is number of angels
so one inside angle is
(90-2)*180 deg / 90 = 88* 2 deg = 176 deg.
measure of exterior angle is 360 - 176 = 184 deg.
Step-by-step explanation:
Given that,
Half of Robert's piece of wire is equal to of Maria's wire i.e.
....(1)
Total length of the wires = 10 feet
ATQ,
....(2)
Use equation (1) in (2).

So,

Hence, this is the required solution.
2560-1944= 616gallons
7 days in a week or 14 days in two weeks
616gallons / 14days = 44 gallons / 1 day
Notice in the fraction we have
(Gallons / days)
Now if you filled the take up the entire way
2560 gallons
We have gallons and the question wants the amount of days
Thus to cancel gallons we set the equation up as such
(2560 gallons) x (1 day / 44 gallons) = 58.18 days
Or 58 days
