Question

In a triangle, if two angles are 60 and 40, then the third angle will be

2 points

40

60

70

80​

Answer 1

Answer:

third angle = 80

Step-by-step explanation:

in triangle,

sum of the angles = 180

60+40+x = 180

100 + x = 180

x = 180 - 100

x = 80

Answer 2

Answer:

So, if we add the angles of the triangle then we get 180 degrees.

So, they have told us the angle of the two sides

Therefore, the third angle = 180 degrees - (40+60) degrees

                      = 180 degrees - 100 degrees

                      = 80 degrees

Hence, the correct answer is 80 degrees.
