How to solve this question?

a. LHS = tan(x) + cot(x)

= {sin(x)/cos(x)} + {cos(x)/sin(x)}

= [{sin(x)}^2 + {cos(x)}^2] / {sin(x)cos(x)}

= 1 / {sin(x)cos(x)}

= 2 / {2sin(x)cos(x)}

= 2 / {sin(2x)}

= 2 cosec(2x) = RHS

b. sorry but idk waht the second ome will be

do you have the measurements?

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
