Question

if cos Ø=3/5 find the value of 5 cosecØ -4 tan Ø/sec Ø+ cosecØ .​

Answer 1

Answer:

cost is 5

Step-by-step explanation:

Answer 2

Answer:

Lets draw the right angle triangle with the above mentioned details

Given thing are

Cosec Θ = 7/11

we know that Cosec Θ = Hypotenuse / Opposite Side, so we get

Opposite Side = 7

Hypotenuse = 11

Hypotenuse : BC = 11

Adjacent Side : AB = ? (Adjacent to ∠ Θ)

Opposite Side : AC = 7 (Opposite to ∠ Θ)

To find the Adjacent Side - AC , we use Pythagoras theorem ((Hypotenuse)2 = (Leg 1)2 + (Leg 2)2)

__________

AB = √ BC2 - AC2

_______

AB = √ 112 - 72

_______

AB = √ 121 - 49

__

AB = √ 72
