Question

cottheta= 5/10,cosectheta=?​

Answer 1

cot theta=5/10

so...cos theta=10/5=2

so....(cos theta)^2=2^2

so.....cos2 theta=4

so.....1-sin2 theta=4

or....sin2 theta=-3

or sin theta = root(3)

or.....cosec theta= 1/root(3)

Answer 2

Cosectheta - cottheta = 1

x - 5/10 = 1

x = 1+ 5/10

= 10+5/10

= 15/10 = 3/2....

hope it help you mate
