Question

If cos =15/17, then find sin ? ​

Answer 1

Answer:

Sin ∆ = 8/17

Step-by-step explanation:

Please refer ∆ as theta.

cos ∆=Adjacent Side/Hypotenuse

cos ∆=15/17

So, Adjacent side is 15 cm.

and Hypotenuse is 17 cm.

So, by Pythagoras theorem we get,

Opposite side = √(Hypotenuse)²-(Adjacent Side)²

Opposite side = √17²-15²

Opposite side = √289-225

Opposite side = √64

Opposite side = √8×8

Opposite side = 8

So, sin∆ = Opposite side/Hypotenuse

Sin∆ = 8/17.

Hence, founded.
