Question

the measures of two angles are given find the measure of the third angle of a triangle 40degree, 70degree​

Answer 1

Answer:

then the third angle is 70°

Answer 2

sum of all angles of triangle= 180°

let,third angle be x

then,40°+70°+x° = 180°

X° =180 - 110°

X=70°

Hence,third angle = 70°

so,that traingle is isosceles triangle.
