Finding the perimeter with all known sides is very easy. All you need to do is add up all of the sides. In this case the answer is 58 in. Hope this helps!
The first answer is right
(x - 9) (x + 9)
It’s me again lol
Answer:
Angle RTS
Step-by-step explanation
Say it out loud it goes, RS, ST.
If you put RS and ST together the angle RTS
It is equal to 9.461 x 10 km
To find the volume we use an equation:
volume = length x width x height
Since this shape is a cube, you only need to know one side to find the volume since all of the sides are equal.
So all you need to find the volume is to multiply 4(1/2) which I am going to simplify to 4.5, is plug it into the equation.
volume = 4.5 x 4.5 x 4.5
Which will get you an answer of 91.125 inches cubed

Hope this helps :)
