The four angles of a quadrilateral are in the ratio of 1 : 2 : 3 : 4. Find the measure of each angle of the quadrilateral. |
|
Answer» Given that, the ratio of angles of a quadrilateral = 1 : 2 : 3 : 4 Sum of the terms of the ratio = 1 +2 + 3 + 4= 10 Sum of the four interior angles of a quadrilateral = 360° ∴ The measure of first angle = 1/10 x 360° = 36° The measure of second angle = 2/10 × 360° = 72° The measure of third angle = 3/10 × 360° = 108° The measure of fourth angle = 4/10 × 360° = 144° |
