How are the angles of an equilateral triangle related?
julia-pushkina [17]
There are 180 degrees in total inside a triangle.

If something is equilateral that means that all the angles are equal.

180/3 equals 60 degrees.

That means that all angles of an equilateral triangle are always equal to each other and if you must know, are 60 degrees

NEED ANSWER ASAP- FOR FINALS
blagie [28]

Answer:

Width - 12ft  Length - 30ft

Step-by-step explanation:

Width is 12ft

Length is 30ft

Depth is 6ft

The length, 30ft, is 2.5 times longer than the width which is 12 ft which confirms the two dimensions to be correct.

When you multiply all three of the dimensions of the swimming pool you will get 2940 cubic feet
