Question

The angles of a quadrilateral are in the ratio 5:7:7:11. Find the measure of each angle.​

Answer 1

Answer:

60°, 84°, 84°, 132°

Step-by-step explanation:

Let the angles be in the form 5x, 7x, 7x, and 11x resp:

In a quadrilateral, sum of angles = 360°

Thus,

5x + 7x + 7x + 11x = 360°

30x = 360°

x = 12°

Thus, the angles are,

5x = 5 * 12 = 60°

7x = 7 * 12 = 84°

7x = 7 * 12 = 84°

11x = 11 * 12 = 132°

Answer 2

Answer:

angles = 5x+7x+7x+11x

30x=180°

x=180°/30

x=60

1st angle= 5×60=300

2nd angle=7×60=420

3rd angle=7×60=420

4rth angle=11×60=660

hope this helps uhh!!!!!
