Answer 2

Answer:

let the first and second angles of the triangle are A and B respectively. And also let third angle be C

so given that,

A= 60°

B=80°

by angle sum property of a triangle

angle A + angle B + angle C = 180°

60° + 80° + C = 180°

140° + C = 180°

C = 180° -140°

C = 40°

so ans. is 40°
