Question

15) The four angles of a quadrilateral are in the ratio 3:4:5:6. Find the angles.​

Answer 1

Answer:

The four angles of a quadrilateral are in the ratio 3 : 4 : 5 : 6. Find the angles. Solution : Let angles be 3x, 4x, 5x, 6x. Thus, 3x + 4x + 5x + 6x = 360° since sum of the angles of a quadrilateral is 360°.

Answer 2

Answer:

Sum of all angles of quadrilateral are 360

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

18x=360

x=360/18

x=20

Step-by-step explanation:

so angles are

3×20=60

4×20=80

5×20=100

6×20=120
