Answer: r = 5
Steps:
![a_n=ar^{n-1}](https://tex.z-dn.net/?f=a_n%3Dar%5E%7Bn-1%7D)
1. add Values to formula
![1250=2r^{5-1}](https://tex.z-dn.net/?f=1250%3D2r%5E%7B5-1%7D)
2. get r alone
➜ ![625= r^4](https://tex.z-dn.net/?f=625%3D%20r%5E4)
3. get rid of the exponents
➜ ![\sqrt[4]{625}= r=5](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B625%7D%3D%20r%3D5)
r = 5

Answer:
Option (B)
Step-by-step explanation:
Since all the four rays A, E, D and F are diverging from a point C in the different directions.
Therefore, sum of all the angles formed at a point C will be equal to 360°
m∠1 + m∠4 + m∠6 + m∠9 = 360°
25° + 34° + 146° + m∠9 = 360°
m∠9 = 360° - 205°
= 155°
Therefore, measure of angle 9 is 155°.
Option (B) will be the correct option.
