Answer 1

Explanation:

Let a = 3x

b = 5x

c = 9x

d = 13x

we know that,

sum of angles of quadrilateral is 360°

a + b + c + d = 360° [angle sum property of quadrilateral]

3x + 5x + 9x + 13x = 360°

30x = 360°

x = 360/30

x = 12

Hence , the angles are

a = 3x

3 × 12 = 36°

b = 5x

5 × 12 = 60°

c = 9x

9×12 = 108°

d = 13x

13 × 12 = 156 °

Answer 2

Answer:

Let the angles of quadrilateral be 3x, 5x, 9x and 13x

let name the angles :

a = 3x ; b = 5x ; c = 9x and d = 13x

sum of all angles of a quadrilateral

= 360° [ property of quadrilateral ]

3x + 5x + 9x + 13x = 360°

30x = 360°

x = 360°/30

x = 12°

then, angle a = 3x = 3 × 12 = 36°

b = 5x = 5 × 12 = 60°

c = 9x = 9 × 12 = 108°

d = 13x = 13 × 12 = 156°
