Answer: D. 44

Step-by-step explanation:

Here, we need to know the concept of trigonometry.

  • Sine (sin) = Opposite/Hypotenuse = O/H
  • Cosine (cos) = Adjacent/Hypotenuse = A/H
  • Tangent (tan) = Oppostie/Adjacent = O/A

-----------------------------------------------------------------------------

Given

- The adjacent side of angle x and the hypotenuse.

- We are going to use Cosine.

<u>Solve</u>

cos (x) = 15/21

       x  = cos⁻¹ (15/21)

       x  ≈ 44

Hope this helps!! :)

faltersainse [42]
You can create a right angled triangle.
Find the hypotenuse.
The third point of the triangle is (1,0)
using pythagoras, the value of a is 2, b is 3. 2^2 +3^2 = 13.
Therefore the distance between the two points is \sqrt{13}
