Hey friend!! here is your answer
_____________________________
◆Cos(20+ theta)=sin30
◆Sin(90-theta)=cos theta
◆Cos(20+theta)=sin(90-60)
◆Cos(20+theta)=Cos60
◆20+ theta=60
◆Theta=60-20
=40

cos (20+theta )=sin30
=cos (20+theta)=cos (90-60)
=20+theta=60
Theta=40
=cos (20+theta)=cos (90-60)
=20+theta=60
Theta=40
The answer to this question is 1 not 10 as written in my book
but 40 is correct dear...and if this ans.is not true then I try to my best....
