In right ∆abc the altitude ch to the hypotenuse ab intersects angle bisector al in point d. find bc if ad = 8 cm and dh = 4 cm.

      Measure of side BC in the figure attached is 24 units.

 Given in the question,

By applying sine rule in right ΔADH,

Therefore,

By applying tangent rule in right ΔAHD,

By applying cosine rule in ΔAHC,

By applying tangent rule in right ΔACB,

units

    Therefore, measure of side BC is 24 units.
