Answer:

√3

Step-by-step explanation:

sin20/(cos20+4sin20 )

(sin20+4sin20cos20)/cos20

2sinAcosA=sin2A

sin(C−D)=sinCcosD−cosCsinD

sin(C+D)=sinCcosD+cosCsinD

(sinn20+2sin40)/cos20

sin20+2sin(60−20)cos20  

(sin20+2{sin60cos20−cos60sin20})/cos20

(sin20+2sin60cos20−sin20)/cos20

(2sin60cos20)/cos20

2sin60

2.√3/2

√3
