Answer:
this one 1/5 = 3 x a
Step-by-step explanation:
1/5 =3×a (divied both side by 3)
a= 1/5 ÷3
Answer:
C
Step-by-step explanation:
We already know that a right angle is 90° and where C is in the picture shows us an obtuse angle making it beleive that it must be above 90°, which leaves us with C as our final answer and is the only answer that makes sense to be correct. Hopefully this helped you.

Given:
The sequence is 25, 20, 15, 10, 5.
To find:
The ninth term of the given sequence.
Solution:
We have,
25, 20, 15, 10, 5
It is an AP because the difference between two consecutive terms are same.
Here,
First term (a) = 25
Common difference (d) = 20-25
= -5
The nth terms of an AP is
![a_n=a+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da%2B%28n-1%29d)
Where, a is the first term and d is the common difference.
Putting a=25, n=9 and d=-5 to get the 9th term.
![a_9=25+(9-1)(-5)](https://tex.z-dn.net/?f=a_9%3D25%2B%289-1%29%28-5%29)
![a_9=25+(8)(-5)](https://tex.z-dn.net/?f=a_9%3D25%2B%288%29%28-5%29)
![a_9=25-40](https://tex.z-dn.net/?f=a_9%3D25-40)
![a_9=-15](https://tex.z-dn.net/?f=a_9%3D-15)
Therefore, the ninth term of the given sequence is -15.
