Question

the angles of a quadrilateral are in the ratio 1:2:4:5 find all the angles of the quadrilateral
​

Answer 1

Answer:

we know that sum of all angles of a quadrilateral is 360..

1x + 2 x + 3x+ 4x = 360

10 x = 360

x = 36

1x = 36

2x = 36 × 2 = 72

3x = 36×3 = 108

4x = 36 ×4 = 144

Hope it helps

Answer 2

Answer:

30° , 60° , 120° , 150°

Step-by-step explanation:

Angles of the quadrilateral are in ratio 1:2:4:5 .

Let the angles be x , 2x , 4x , 5x .

x+2x+4x+5x = 360°

12x = 360°

x = 30°

Hence the angles are :-

x. = 30°

2x = 60°

4x = 120°

5x = 150°
