Question

pls solve me the answer i make u brainlist

Answer 1

one angle is 55* as it is isosceles
other is also 55*

let the third angle be x
55+55+x =180*
X=70*

hence all angles are 55*,55*,70*

Answer 2

in an isosceles triangle two sides r equal and sum of all angles is 180*,
so,
55*+55*+x=180*
110*+x=180*
x=70*

hence remaining angle is 70*
