Question

Given that the triangles shown below are similar, what is the value of x?25D31°31°M15AL 3 EA. 5B. 15C. 10D. 1.8

Answer 1

According to the given information, the triangles are similar, which means that the following proportion can be stated:

`(MS)/(MA)=(LD)/(LE)`

Replace for each value:

`(25)/(15)=(x)/(3)`

Solve the proportion for x:

`\begin{gathered} 3\cdot(25)/(15)=x \\ x=(25)/(5) \\ x=5 \end{gathered}`

x has a value of 5. According to this, the correct answer is A. 5.
