Question

If an exterior angle of a triangle is 110 and its opposite interior angle is 40 then the other two angles are equal to

Answer 1

outer angle = 110


interior 1st angle = 40

=> 2nd angle = 110 - 40 = 70


so the two angles of the triangle are 40 and 70 so third angle will be 180 - (40 + 70)

as sum of all angles are always 180

=> 180 - (40 + 70)
=> 180 - 110
=> 70


hence other 2 angles are 70 and 70 degree.
