Answer 1

Question:-

Solve  for  the  unknown  side   by  applying  the  Triangle  Angle‐Bisector  Theorem.

Solution for r:-

$\rightarrow\sf{\frac{25}{15}=\frac{s}{18}\rightarrow{15s}=25(18)}$

$\rightarrow\sf{s=\frac{25(18)}{15}}$

$\rightarrow\sf{s={\frac{[(5)(5)][(2)(3)(3)]}{(3)(5)}}}$

$\rightarrow\sf{s=(5)(2)(3)=30}$

Solution for s:-

$\rightarrow\sf{s=20-r=20-12={\color{magenta}{8}}}$

Answer:-

• The Unknown sides of the given figure above is 8.
