Question

The four angles of A quadrilateral are in the ratio 2:3:4:5. find the angles​

Answer 1

Step-by-step explanation:

ratio = 1:3:4:5

Let the angles be x , 3x , 4x ,and 5x

sum of all angles of a quadrilateral = 360°

so,

x+3x+4x+5x = 360

$= > 12x = 360$

$= > x = \frac{360}{12}$

=> x= 30°

so the angles are ,

1×30=30°

3×30=90°

4×30=120°

5×30=150°
