Question 2

ABC is a triangle. The bisectors of the internal angle $$\angle$$B and external $$\angle$$C intersect at D. If $$\angle$$BDC=$$50^{\circ}$$, then $$\angle$$A is


In $$\triangle$$ BDC,

=> $$y+(180^\circ-2x+x)+50^\circ=180^\circ$$

=> $$y-x+50^\circ=0$$

=> $$y-x=-50^\circ$$

In $$\triangle$$ ABC,

=> $$2y+(180^\circ-2x)+\angle A=180^\circ$$

=> $$2(y-x)+\angle A=0$$

=> $$2(-50^\circ)+\angle A=0$$

=> $$\angle A=100^\circ$$

=> Ans - (A)
