Question

can someone help me

Answer 1

Because the two triangles are similar we know that \[\frac{3}{x+1}=\frac{7}{3x-1}\]Solve for x.

Answer 2

i got confused similar in terms of? shape?

Answer 3

Since both triangles are similar, that means to shows that the sides of the triangle are equal IN PROPORTION. *note, they are not equal in value, they are equal only in proportion.

Thus equating the proportionality,

\[\frac{x+1}{3}= \frac{3x-1}{7}\]

7(x+1) = 3( 3x-1)
7x+7 = 9x-3
2x = 10
x= 5.

Thus side 3x-1 is equals to 14.
