Angle Bisector Theorem
-------------------------------------
*Assuming BD bisects ∠ABC
[tex] \dfrac{AD}{DC} = \dfrac{AB}{BC} [/tex]
-------------------------------------
Fid the ratio
-------------------------------------
[tex] \dfrac{AD}{DC} = \dfrac{36}{27} [/tex]
-------------------------------------
Simplify
-------------------------------------
[tex] \dfrac{AD}{DC} = \dfrac{4}{3} [/tex]
-------------------------------------
Given ratio, find CD
-------------------------------------
Ratio of AD : DC = 4 : 3
Given that AC = 42 cm
7 shares = 42 cm
1 share = 42 ÷ 7
1 share = 6 cm
3 shares = 6 x 3
3 shares = 18cm
