Answer:

Lets draw the right angle triangle with the above mentioned details

Given thing are

Sin Θ = 5/7

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

Opposite Side = 5

Hypotenuse = 7

Hypotenuse : BC = 7

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

Opposite Side : AC = 5 (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 = √ 72 - 52 

 AB = √ 49 - 25 

AB = √ 24 

Now we will try to simplify square root of 24 and we get (2 x 2 x 2 x 3). Take out pairs and we get

 AB = 2 √ 2 x 3  

 AB = 2 √ 6  

So Sin, Cos and Tan will be as follows -

Sin Θ = Opposite Side / Hypotenuse

Sin Θ = 5 / 7

Tan Θ = Opposite Side / Adjacent Side

 Tan Θ = 5 / 2 √ 6 

Cos Θ = Adjacent Side / Hypotenuse

 Cos Θ = 2 √ 6  / 7
