<h3>Solution:</h3>
- The sum of all the angles which stand on a straight line is 180°.
- Therefore,
- 2z + 140° = 180°
- or, 2z = 180° - 140°
- or, 2z = 40°
- or, z = 40° ÷ 2
- or, z = 20°
<h3>Answer:</h3>
z = 20°
Hope it helps! Please do comment if you have any query.

180-140=40 (complementary angle)
2z=40
Z=40/2
Z=20
