Question

P(5,12)
find cosec theta?

Answer 1

`(13)/(12)`

Explanation:

`p(5, \: \: 12) = (x, \: \: y) \\ \implies \: x = 5, \: \: y = 12 \\ \because \: {r}^(2) = {x}^(2) + {y}^(2) \\ \therefore \: {r}^(2) = {5}^(2) + {12}^(2) = 25 + 144 = 169 \\ \therefore \: {r} = √(169) \\ \therefore \: {r} = 13 \\ \because \cosec \theta = (r)/(y) \\ \therefore \cosec \theta = (13)/(12) \\`
