We know that the sum of interior opposite angles of triangle is equal to the exterior angle.
So, the other interior opposite angle will be 80° (120-40)
We can find the remaining angle by Angle Sum property,
180-(80+40)
=180-120
=60°
So, the other interior opposite angle will be 80° (120-40)
We can find the remaining angle by Angle Sum property,
180-(80+40)
=180-120
=60°
