Question

4)lf 5 cosA=3 then value of (cosech-
cotA)/(cosecA+cotA) is: *​

Answer 1

Step-by-step explanation:

cosA=3/5=B/H

by.P.T

• H

Answer 2

Answer:

1/4

Step-by-step explanation:

cos A= 3/5

base=3

hypotenuse=5

therefore, perpendicular= 4 (using PGT)

Cosec=h/p

cot=b/p

cosecA=5/4

cotA=3/4

now,

substituting the values.

(5/4-3/4)/(5/4+3/4)

=> (2/4)/(8/4)

=> 1/4
