Question

the ratio of four angles of quadrilateral 1:4:3:4 find the angles​

Answer 1

Answer:

Let the four angles be 1x, 4x, 3x and 4x respectively.then,

1x + 4x + 3x + 4x = 360° (Sum of all angles of a quadrilateral is 360°)

=> 12x = 360

=> x = 360/12

=> x = 30°

hence, first angle = 1x = 1 x 30° = 30°

second angle = 4x = 4 x 30° = 120°

third angle = 3x = 3 x 30° = 90°

fourth angle = 4x = 4 x 30° = 120°
