Question

if angles A, B, C and D of the quadriletral ABCD, taken in order, are in the ratio 3:7:6:2, then find all angles of quadriletral ABCD​

Answer 1

Answer:

60°, 140°, 120°, 40°

Step-by-Step Explanation:

3x+7x+6x+2x=360

18x=360

x=360÷18

x=20

The angles are—

3x=20×3=60°,

7x=20×7=140°,

6x=20×6=120°,

2x=20×2=40°

Answer 2

Answer:

angle A = 60 degree

angle B = 140 degree

angle C =120 degree

angle D = 40 degree
