Triangles LMN and NWR are right triangles. What is
Sever21 [200]

Answer:

NW = 15.6 cm

Step-by-step explanation:

If ΔLMN ~ ΔNWR then:

\sf LN : LM = RN : RW

\implies \sf \dfrac{LN}{LM}=\dfrac{RN}{RW}

\implies \sf \dfrac{10}{24}=\dfrac{6}{RW}

\implies \sf 10RW=6 \cdot 24

\implies \sf RW = 14.4\:cm

Find NW by using Pythagoras' Theorem:

a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Given:

  • a = RN = 6 cm
  • b = RW = 14.4 cm
  • c = NW

Substituting the given values into the formula and solving for NW:

\implies \sf 6^2+14.4^2=NW^2

\implies \sf NW^2=243.36

\implies \sf NW=\sqrt{243.36}

\implies \sf NW=15.6\:cm
