Question

9) The four angles of a quadrilateral are in the ratio 1:2 : 3:4. The measure of its smallest angle is?

O a) 120°
Ob) 36
O c) 180°
O d) 10°​

Answer 1

Answer:

hey smallest angle is 36⁰

follow me

because let the common ratio be x

so it will be 1x ,2x,3x,4x

then sum of all angles of quadrilateral is 360⁰

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

10x= 360

x= 360/10

x = 36
