Question

The angles of a quadrilateral are
in the ratio 3:4:5:6. The respective
angles of the quadrilateral are
O 1200, 1000, 80°, 60°
O 600, 800, 1000, 1200
.
O 120°, 60°, 800, 100°
O 800, 1000, 120°, 60°​

Answer 1

Hello...

Let first angle be 3x°,

second angle be 4x°,

third angle be 5x° and

fourth angle be 6x°

We know that sum of all angles of a quadrilateral is 360°.

So, 3x+4x+5x+6x = 360

=> 18x = 360

=> x = 20

first angle = 3x° = 3 × 20 = 60°

second angle = 4x° = 4 × 20 = 80°

third angle = 5x° = 5×20 = 100°

fourth angle = 6x° = 6×20 = 120°

Hope this will help you mate ✌✌✌
