Question

If Cot A = 5/7 then find the cosec A, tan A, Sec A.

Answer 1

cot A = 5/7

☞ tan A = 1/cot A = 7/5.

☞ sec^2 A = 1 + tan^2 A.
(secA)^2 = 1 + (tanA)^2
(secA)^2 = 1 + (7/5)^2
(secA)^2 = 74/25
sec A = root74 ÷ 5 ____ is the ans.

☞ Similarly, cosec^A = 1 + cot^2A
So, put the value of cot A in above identity.
We get,
cosec A = root74 ÷ 7.......

Hope this will help you.......
Have u any doubt then ask me.
