Question

in a Quadrilateral ABCD the angles A, B and C are in the ratio 2:3:1 and D=60 degree, find other angles.

please help. ​

Answer 1

Answer:

Step-by-step explanation:

∠A:∠B:∠C:∠D=1:2:3:4

So, let ∠A=x,∠B=2x,∠C=3x,∠D=4x

Therefore, by angle sum property of quadrilateral,

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

10x=360

x=36

Hence,

∠A=36

,∠B=72  

o

,∠C=108  

o

,∠D=144
