Pls answer this question, it is one question only

Answer 1

Hii

you are welcome in my ans

cos(90- 20)/sin20 +{ cos55 /sin(90 - 35)}/tan(90- 85) *tan(90-65)*1*tan65*tan85)}

since

cos(90 - 20) =sin20

tan(90 -65)=cot65

tan(90-85)=cot85

sin(90-55)=cos55

sin20/sin20 + (cos55/cos55)/cot65*tan65*cot85*tan85

since

cot65*tan65=1

cot85*tan85=1

so

1+ 1/1

=2
