Question

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

Answer 1

Answer:

we know that sum of angles in a parallelogram is equal to 360°

so,

sum of angles=

3x+4x+5x+6x=360° --1

18x=360°

x=20

substitute x in equation 1

3x = 3×20=60°

4x = 4×20= 80°

5x = 5×20= 100°

6x = 6×20 =120°

therefore angles are 60°,80°,100°120°
