Answer 2

Answer:

30° , 90° and 150°

Step-by-step explanation:

let the angle be 1x, 3x and 5x

therefore,

1x + 3x + 5x + 90° = 360° (angle sum property of a quadrilateral)

9x = 360 - 90 = 270°

x = 270/9 = 30

therefore x = 30

therefore angles are,

1x = 30°; 3x = 3 × 30 = 90° and 5x = 5 × 30 = 150°
