Answer: Option d.

Step-by-step explanation:

You need to use the trigonometric identities:

sin\theta=\frac{opposite}{hypotenuse}\\\\cos\theta=\frac{adjacent}{hypotenuse}\\\\tan\theta=\frac{opposite}{adjacent}

Identify the opposite side, the adjacent side and the hypotenuse in the right triangle:

opposite=9\\adjacent=12\\hypotenuse=15

Substituting these values into the corresponding identity, you get:

sin\theta=\frac{9}{15}\\\\cos\theta=\frac{12}{15}\\\\tan\theta=\frac{9}{12}

Answer:

The correct answer is option d

Step-by-step explanation:

From the given figure we can see that, a right angled triangle.

<u>Points to remember </u>

Sinθ = Opposite side/Hypotenuse

Cosθ = Adjacent side/Hypotenuse

Tanθ = Opposite side/Adjacent side

Let the angle be θ

<u>To find sine, cosine, and tangent  </u>

Sinθ = Opposite side/Hypotenuse = 9/15

Cosθ = Adjacent side/Hypotenuse = 12/15

Tanθ = Opposite side/Adjacent side = 9/12

The correct answer is Option d
