Given the following triangle find side AC. <br><br> A. 11.89<br> B. 12.87<br> C. 13.98<br> D. 14.08
BigorU [14]

Answer:

The answer to your question is AC = 14

Step-by-step explanation:

To solve this problem, we must use trigonometric functions.

And we must look for a trigonometric function that relates the opposite side and the hypotenuse.

This trigonometric function is the sine

   sin\alpha  = \frac{opposite side}{hypotenuse}

solve for Opposite side = AC

  AC = hypotenuse x sin α

- Substitution

  AC = 25 x sin 34

- Simplification

  AC = 25 x 0.56

- Result

  AC = 14

PLEASE HELP! 20 POINTS!! PIC ATTACHED :)
leonid [27]

From the figure, we immediately have

cos(θ) = 8/17

sin(θ) = 15/17

By definition of tangent,

tan(2θ) = sin(2θ)/cos(2θ)

Recall the double angle identities:

sin(2θ) = 2 sin(θ) cos(θ)

cos(2θ) = cos²(θ) - sin²(θ) = 2 cos²(θ) - 1

Then

tan(2θ) = (2 sin(θ) cos(θ)) / (2 cos²(θ) - 1)

tan(2θ) = (2 × 15/17 × 8/17) / (2 × (8/17)² - 1)

tan(2θ) = -240/161
