Answer 1

Let the angle we x, 2x & 3x as per the given ratio respectively.

By given condition,

We can write,

x + 3x = 180°

4x = 180°

x = 45°

Therefore the angles will be ,

x = 45°

2x = 45×2 = 90°

3x = 3×45 = 135

Remaining last angle will be = 360 - 135+90+45

= 90°

So the angle of a quadrilateral is are 45°, 90°, 135 & 90° respectively.

Answer 2

Step-by-step explanation:

Let the angle be x

1x + 2 x + 3x = 180°

6x= 180°

x= 180/6

x= 30°

1st angle = 30°

2nd angle = 2× 30= 60°

3rd angle = 3× 30= 90°

4th angle = 4× 30= 120°
