Question

The angle of a quadrilateral are in the ratio 4: 4: 5: 5.Find the measure of each angle.​

Answer 1

Answer:

$4x + 4x + 5x + 5x = 360 \\ 18x = 360 \\ x = \frac{360}{18 } \\ x = 20 \\ so \: angles \: are \: 80. \: 80.100.100degrees$

Answer 2

Answer:

4x + 4x + 5x + 5x = 360

18x = 360

x = 20

4x = 80

5x = 100                                                                                                                                                                                                                                            Step-by-step explanation:
