Question

if four angles of a quadrilateral are in ratio 3:8:4:9 find the smallest angle​

Answer 1

Answer:

Let the angles be in the form of x

so...

3x+8x+4x+9x=360

24x=360

x=360/24

x=15...

Answer 2

Answer:

Ratio=3:8:4:9

Let the common see be=x

3:8:4:9=3x:8x:4x:9x

Sum of all sides of quadrilateral=360 degree

3x+8x+4x+9x=360 degree

24x=360

x=360/24=15

x=15

3x=3*15=45

8x=8*15=120

4x=4*15=60

9x=9*15=135

So, the sum of the smallest side is 45 degree
