Question

If two
angles of a quadrilateral
measures 20° and 160° and the
other two are in ratio 4:5. Find
angle of quadrilateral​

Answer 1

Answer:

80°, 100°

Step-by-step explanation:

Sum of a quadrilateral's angles is 360°

20° + 160° = 180°

360° - 180° = 180°

4:5

4x + 5x = 9x

9x = 180°

X = 20

4x = 80°

5x = 100°
