Question

(A) What did Cuss see in Room Eight? What did it result into at the end of the story land on the earth?​

Answer 1

Explanation:

(cos 45°)/(sec 30° + cosec 30°)

`=(1/sqrt2)/(2/sqrt3+2) = (1/sqrt2)/((2+2sqrt3)/sqrt3)`

`= sqrt3/(sqrt2(2+2sqrt3)) = sqrt3/(2sqrt2+2sqrt6)`

`= (sqrt3(2sqrt6-2sqrt2))/(((2sqrt6)+2sqrt2)(2sqrt6-2sqrt2))`

`= (2sqrt3(sqrt6-sqrt2))/((2sqrt6)^2 - (2sqrt2)^2) = (2sqrt3(sqrt6-sqrt2))/(24-8)= (2sqrt3(sqrt6-sqrt2))/16`

`= (sqrt18-sqrt6)/8 = (3sqrt2 - sqrt6)/8`
