Determine the sine, cosine, and tangent of the angle.

Option d.

Step-by-step explanation:

You need to use the trigonometric identities:

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

Substituting these values into the corresponding identity, you get:

The correct answer is option d

Step-by-step explanation:

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

Points to remember

Sinθ = Opposite side/Hypotenuse

Cosθ = Adjacent side/Hypotenuse

Tanθ = Opposite side/Adjacent side

Let the angle be θ

To find sine, cosine, and tangent  

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

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
