Question

angles of a quadrilateral are in the ratio 2:3:5:8. Find the measures of the smallest angle​

Answer 1

Answer:

The ratio of angles of quadrilateral are 2:3:5:8

⇒  Let the four angles be 2x,3x,5x and 8x

We know, sum of four angles of quadrilateral is 360  

o

 

∴  2x+3x+5x+8x=360  

o

 

⇒  18x=360  

o

 

⇒  x=20  

o

 

The angles are,

⇒  2x=2×20  

o

=40  

o

 

⇒  3x=3×20  

o

=60  

o

 

⇒  5x=5×20  

o

=100  

o

 

⇒  8x=8×20  

o

=160  

o

 

∴  The smallest angle of the quadrilateral is 40
