Two triangles are similar if the only difference between them is the size, this means that their internal angles must be the same. If we look at the picture the first triangle has one angle equal to 40 degrees, one equal to 80 degrees and the third one is unkown (x). The second triangle has one angle equal to 40 degrees, one equal to 60 degrees and the third one is unkown (y). The sum of the internal angles of a triangle must be equal to 180 degrees, with this information we can find the values of the missing angles. We have:

\begin{gathered} 40+80+x=180 \\ 120+x\text{ = 180} \\ x\text{ = 180-120=60} \end{gathered}\begin{gathered} 40+60+y=180 \\ 100+y=180 \\ y=180-100=80 \end{gathered}

Therefore the internal angles of the first triangle are (40,80,60) and the angles of the second triangle are (40,80,60) as well, therefore they are similar.

Two triangles are congruent if they have sides with the same length. Which is not the case, because the sides of one triangle is (8, 10, 6) while the other is (4,3 and unkown). Therefore they are not congruent.

Answer:

Step-by-step explanation:

x² - y² =  (x + y)(x-y)

c² - (5b - 3a)² = (c + [5b -3a]) ( c - [5b - 3s] )

                     = (c + 5b - 3a) (c - 5b + 3s)

Answer:

C. a numerical expression.

Step-by-step explanation:

Right away, what you should know is that this is an expression. Equations are expressions, except wiht an equal sign. This is not algabraeic though, since there is no valuable (for example 3x, or 7a). So, through the process of elimination, the answer would be a numerical expression.

Hope this helps!
