Answer» The ANGLES of a quadrilateral are :90°, 45°, 100°, 125°Step-by-step explanation:LET, The angles of a quadrilateral be:18x9x20x25xWe know that,Sum of all angels of a quadrilateral is 360°So,⇒ 18x + 9X + 20x + 25x = 360⇒ 72x = 360⇒ x = 360 / 72⇒ x = 5★ Value of 18x :⇒ 18 (5)⇒ 90__________________________★ Value of 9x :⇒ 9 (5)⇒ 45_________________________★ Value of 20x :⇒ 20 (5)⇒ 100_________________________★ Value of 25x :⇒ 25 (5)⇒ 125_________________________Therefore,The angles of a quadrilateral are :90°, 45°, 100°, 125° |
