Description: In Δ ABC, the median AD is 6 cm and CB is 12 cm, measure of angle CAB is

Solution

AD = 6 cm and BC = 12 cm

Since, AD is the median, => BD = DC = 6 cm

In $$\triangle$$ ADC, => AD = CD = 6 cm

=> $$\angle$$ DCA = $$\angle$$ DAC = 45°

Similarly, in $$\triangle$$ ADB => $$\angle$$ DAB = 45°

$$\therefore$$ $$\angle$$ CAB = $$\angle$$ DAC + $$\angle$$ DAB = 45° + 45° = 90°

=> Ans - (A)
