Answer 1

Answer:

plzzz follow me .......

Answer 2

Answer:

(X-60)+(2X+40)+(2X-80) = 180 degree..........(cause sum f all 3 angles f a                       triangle = 180 degree)

now,

        X-60+2X+40+2X-80 = 180

        5X-100 = 180

        5X = 180+100 = 280

          X =  280/5 = 56  degree
