Step-by-step explanation:
❍ Given :
- Ratio of the angles of a quadrilateral is 3:5:9:13
❍ To Find :
- Angles of the quadrilateral
❍ Solution :
★ Let the angles be 3x, 5x, 9x and 13x.
Sum of all the angles of a quadrilateral is 360°.
➠ 3x + 5x + 9x + 13x = 360°
➠ 30x = 360°
➠ x = 360/30
➠ x = 12
Value of x is 12.
❒ The angles are :
◘ 3x = 3 × 12 = 36°
◘ 5x = 5 × 12 = 60°
◘ 9x = 9 × 12 = 108°
◘ 13x = 13 × 12 = 156°
∴ The angles of a quadrilateral are 36°, 60°, 108° and 156°.
❍ Verification :
⇛ 36° + 60°+ 108° + 156° = 360°
⇛ 360° = 360°
Hence, Verified.
