Question

An exterior angle of a triangle is 120º and one of its interior opposite angles is 40º. Then find the other two angles in degree.

Answer 1

Answer:

other 2 angles are 60 and 80 degrees

Step-by-step explanation:

let one of the opposite angle x

x + 40 = 120

x = 80, one of the opposite angle

we know that all angles of a triangle = 180

let remaining angle be 'y'

40 + 80 +y = 180

120 + y = 180

y = 60.
