Evaluate the six trigonometric functions of the angle 0?

Step-by-step explanation:

In the above right Angled triangle , we have ,

For finding hypontenuse use Pythagoras Theorem , we have ,

⇒ h² = p² + b²

⇒ h² = 9² + 12²

⇒ h² = 81 + 144

⇒ h² = 225

⇒ h = √225

⇒ h = ± 15

⇒ h = 15 [ Neglect -ve value ]

Therefore ,

using pemdas, (order of operations) you'll see the answer is 24.
