Question

The angles of a quadrilateral are in the ratio 2:3:5:8. Find the measures of the smallest angle.​

Answer 1

→→ suppose the angles measure 2x,3x,5x,8x

→→ sum of all angles of a qadrilteral are 360°

→→ so 2x+3x+5x+8x = 360

→→ 18x = 360°

→→ x = 20°

→→ smallest angle= 2x = 20×2=40

→→ so answer is 40°
