No it is not an arithmetic sequence because there is no common difference.
9-5=4 and 15-9=6
4!=6
So there is no common difference.
Answer:

sorry if it is wrong
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!! :)
