Question

three angles of a quadrilateral are in the ratio 2:5:6. If the fourth angle measures 100° , find the other three angles of a quadrilateral.​

Answer 1

Answer:

2x = 40°, 5x = 100°, 6x = 120°

Step-by-step explanation:

2x + 5x + 6x + 100° = 360° (ASP of a quadrilateral)

13x + 100° = 360°

13x = 260°

x = 260/13

x = 20°

Therefore, 2x = 40°, 5x = 100°, 6x = 120°
