V = length×width ×height
V = 9 × 2 × 3
V = 54 units cubed
Here we get the statement:
"sec^-1(0.5) is undefined"
And we want to see if this is true or false, so let's use the properties that we know to find that this is false.
Remember that the sec function is defined as:

Then we will have:

Then is really trivial to see that:

Then we can conclude that the function is not undefined at 0.5, so the statement is false.
Below you can see the graph of the given function, and you will see that it is never undefined.

It depends on what you mean by "what can be used", you can use a protractor or ruler since it's a line segment. OR you can use the formula a^ + b^ = c^ to find out all the measurements.......
If you still can't find it, then, you can try to find the other measurements around that specific line segments. And it DEPENDS on what you choose to find the length of this segment.
( There's no picture on my screen, so I'm guessing that you didn't put any.. )
Well, I hope this can help you :3

The answer for this would be b
Answer: At least two sides are congruent
Step-by-step explanation:
Here is the complete question:
If a triangle JKL is classified as isosceles, which statement is true?
a. At least two sides are congruent.
b. Two sides are perpendicular.
c. All three sides are congruent.
d. Two sides are parallel.
An isosceles triangle is a triangle that has at least two sides that are equal. An isosceles triangle has two equal sides and also two equal angles.
An angle is said to be congruent if it has the same angle either in degrees or radians. Such angles don't necessarily have to point in same direction. Therefore, it is true that at least two sides are congruent.
