The two traingles, VSU and TSR are similar by SAS similarity criteria.

According to the diagram,
UT = TS
and
VR = SR


\frac{ST}{SU}  =  \frac{ST}{ST + SU}   \\ =  \frac{ST}{2ST}   =  \frac{1}{2}

Similarly for all sides the ratio must be same.
Applying this on the side required here,

\frac{RT}{VU}  =  \frac{1}{2}   \\  \\  \frac{p - 6}{p}   =  \frac{1}{2}  \\  2p - 12 = p \\  p = 12


Therefore p = 12 units= UV .

Given that the triangles shown below are similar, what is the value of x?
Montano1993 [528]

Using proportions, it is found that the value of x is of x = 5, hence option A is correct.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Since the triangles are similar, the lengths are proportional. Researching the problem on the internet, we have that the proportions are given as follows:

  • A side with a length of x is proportional to a side with length 25.
  • A side with a length of 3 is proportional to a side with length 15.

Hence:

\frac{x}{25} = \frac{5}{25}

Simplifying the denominators:

x = 5.
