Question

Two angles of a triangle are 40 degrees and 60 degrees .find the third angles

Answer 1

As we know that the sum of all angles of a triangle is 180°


40°+60°+third angle =180°

100° + third angle =180

Third angle =180°-100°

Third angle =80°

Answer 2

hey frnd

here is ur answer

given :-

2 angles of triangle are 60°;40°

v all know that sum of interior angles of a triangle is 180°

let' the 3rd angle be c

so


60+40+c°=180°

100°+ c°=180

c°=180°-100°

c°=80°

so the third angel of the given triangle is 80°
