Select the postulate that is illustrated for the real numbers 5+(-5)=0

This is the Addition Inverse postulate.  

Step-by-step explanation:

Consider the provided real number 5+(-5)=0

We need to determine the postulate that is illustrated for the real numbers 5+(-5)=0.

The additive inverse of the number "x" is the number that produces zero when added to "x". Also known as the opposite number.

For example: x+(-x)=0

Where x is any real number and -x is the opposite of x.

Now consider the provided number.

5+(-5)=0

Here the sum or 5 and -5 is 0.

Thus, this is the Addition Inverse postulate.  

idk the answer but just put a

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
