Question

if 1/cos x = cosec 40 what is X

Answer 1

Hope this helps you

Answer 2

Answer:

x = 50.

Step-by-step explanation:

Formula required:

cos x = 1/sec x

sec x = 1/cos x

Also,

cosec x = sec (90 -x).

Solution:

Given equation is 1/cos x = cosec 40.

Using above formula, let's rewrite the given equation as below.

sec x = sec (90 - 40)

sec x = sec 50

Therefore,

x = 50.

(i.e.) 1/cos 50 = cosec 40.

Hope it helps.
