Question

in the adjoining figure ABCD quadrilateral such that angle D + angle C=100 degree the bisectors of a AngleA and angle B meet at angle P determine angle APB. .

Answer 1

SUM OF THE ANGLES OF QUADRILATERAL IS 360 ,IF D+C=100 THEB REMAINS WILL 260 AND FROM THE GIVEN QUE THERE IS BISECTORS OF A& B THEN 260/2=130 AND THE TOTAL ANGLES OF TRNGLE 180 THEN THE 180-130=50 HENCE THE APB=50°
