Question

The four angles of quad. are in the ratio 3:4:5:6.Find all angles​

Answer 1

Step-by-step explanation:

Le the ratio of int. angles of quad be 3x:4x:5x:6x

We know that the sum of aa

ll int. angles of a quad. is 360°.

A/q

3x +4x +5x +6x = 360°

=> 18x = 360°

=> x = 360°/18

x = 20°

Now ,

1st angle = 3x = 3 × 20° = 60°

2nd angle = 4x= 4×20° = 80°

3rd angle = 5x = 5 × 20° =100°

4th angle = 6x = 6× 20° = 120°

Ans...

Answer 2

Answer:

Dear here is your answer :-

The sum of quadrilateral =360

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

18x=360

x= 360-18

342..

Then. 342 x 3 = 1026

342 x 4= 1368

342 x5. = 1710

342. x. 6. =2052
