Which set of values could be the side lengths of a 30-60-90 triangle?
2 answers:
Answer:
Let us take 4,,8
Step-by-step explanation:
When you have a 30-60-90 triangle, your sides will always have a set pattern.
The side across from the 30 angle will be equal to n (so n = 4).
The side across from the 60 angle will always be equal to n√(3) (so 4√(3)).
The side across from the 90 angle will always be 2n (so, 8).
You could go into trig or Pythagorean theorem to prove this, but it's much simpler to remember it because it's a special triangle.

Answer:
The volume of water in the fish tank is 4.5 cubic feet
see the explanation
Step-by-step explanation:
<u><em>The complete question is</em></u>
Explain how you found the volume of water in the fish tank if it was only 1/2 full with water. Show your work and solution. Don't forget your UNITS!
You have a fish tank with the following dimensions:
Height: 3 feet
Width: 1.5 feet
Length: 2 feet
step 1
Find the volume of the fish tank
The volume of a rectangular prism ( fish tank) is equal to
substitute the given values
step 2
Find the volume of water in the fish tank
Remember that
The fish tank it was only one and a half full with water
so
Multiply the volume of the fish tank by one and a half to obtain the volume of water
