Answer 1

angle sum property of triangle will be used
let angles b and c be x
x+x+70=180
2x=110
x=55
angle b and c=55

Answer 2

Hey there !!!!!!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

According to question A=70° AB=AC

Isosceles Triangle is a triangle in which two sides are equal and two angles are also equal.

So B=C

Sum of angles in a triangle = 180°

70°+B+C=180°

B+B=180-70

2B=110°

B=55°

B=C

So  C= 55°

A=70° B=55° C=55°
