Is there any way you could explain this to me?
The square of 18 is 9 because square = 2, so 18 ÷ 2 = 9. I hope this helps you.
Answer:
12.48 gallons
Step-by-step explanation:
Subtract the starting amount from the ending amount
18.18 - 5.7
and get 12.48
Let G be some point on the diagonal line away from point E.
Angle DEG represents angle 1.
We're given that angle DEF is a right angle which means it's 90 degrees. Angle DEG is some angle smaller than 90 degrees. By definition, that must mean angle 1 is acute. Any acute angle is smaller than 90 degrees. There's not much else to say other than this is just a definition problem.
----------------
Extra side notes:
If angle 1 was a right angle, then that would mean angle GEF would have to be 0 degrees; however the diagram shows this isn't the case.
If angle 1 was obtuse, then there's no way we'd be able to fit it into angle DEF. In other words, there's no way to have an angle larger than 90 fit in a 90 degree angle.
