Question

.both the sums................

Answer 1

Sorry bro I don't know 1 sum
2 --
cot = 40\9
As we know that cot = adj\opp
Therefore 40 is adj
9 is opp
Therefore to find hyp
(40)square + (9)square = (hyp)square. Pythagoras theorem
1600+81=(hyp) square
1681=(hyp) square
square root (1681)=hyp
41=hyp
Therefore cosec = hyp\opp
cosec = 41\9

Hope so it helps!!
