Question

two angles of a traingle are 40 degree and 60 degree find the third angle​

Answer 1

Answer:

80

Explanation:

sum of all the angles of a triangle=180

therefore,

60+40+x=180  (x being the third angle)

100 + x=180

x=80 degree

Answer 2

Answer:

40+60+X=180(sum of andgle of triangle is 180)

100+X=180

X=180-100

X=80

therefore third angle is 80
