Question

If cosecA =17/8 then find the value of cos A and cot A.​

Answer 1

Step-by-step explanation:

Given, cosecA=

8

17

⇒sinA=

cscA

1

=

17

8

We know sin

2

A+cos

2

A=1

⇒cos

2

A=1−sin

2

A

⇒cos

2

A=1−

289

64

⇒cos

2

A=

289

225

⇒cosA=

289

225 = 1715

We also know tanA=

cosA

sinA

⇒tanA=

15
