Answer» In triangle ABC, angle A+ Angle B +angle C=18075+50+angle C=180angle C=180-125angle C= 55Due to vertically opposite angles, angle C=55 in ΔCDE angle D+ angle E +angle C=180x+45+55=180x=180-100x=80 Hence, the answer is none of these

Answer»

In triangle ABC, angle A+ Angle B +angle C=18075+50+angle C=180angle C=180-125angle C= 55Due to vertically opposite angles, angle C=55 in ΔCDE

angle D+ angle E +angle C=180x+45+55=180x=180-100x=80

Hence, the answer is none of these
