Answer 1

Question:-

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

Solution for r:-

`\rightarrow\sf{(25)/(15)=(s)/(18)\rightarrow{15s}=25(18)}`

`\rightarrow\sf{s=(25(18))/(15)}`

`\rightarrow\sf{s={([(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.
