Step-by-step explanation:

Solution

Let the other 2 angles be x

 \bf140 \degree + x + x = 180 \degree

By angle sum property

 \sf140 \degree + 2x = 180  \degree \\  \sf2x = 180  \degree \: - 140  \degree \\  \sf \: 2x = 40 \degree \\  \sf \: x =   \frac{40 \degree}{2}  \\  \sf \: x = 20 \degree \\  \bf \:  \therefore \:  the  \: other  \: 2 \:  angles  \: are \:  20  \degree
