​

Answer 1

Answer:

Yes I think he is correct

Step-by-step explanation:

as rohan know the one angle degree then, if angleA is 70 degree than angleB =angleC=x then angle A +angle B + angle C=180 degree therefore 70 degree + x+x=180 degree . x+x=180-70 . x+x = 110 2x=110 . x= 55 degree. therefore we find angleC and angleB that is 55 degree.
