Question

In triangle abc angle A +B =80 angle B +angle C =150 find measure of each angle of traingle ABC​

Answer 1

Answer:

A = 30°, B =50° , C = 100°

Step-by-step explanation:

A+B =80°; B+C =150°

on adding, A+2B+C = 80+150=230°

but A+B+C =180° (∵Sum of the angles in a triangle)

A+B+C+B =230

180+B =230

B =230-180 =50°

A+B =80⇒ A =80 -50 =30°

B+C= 150 °⇒ C = 150 - 50 = 100°
