The value of 4b/a is 240.
Step-by-step explanation:
Given,
a x 60 = b
or
b = a x 60
Similarly, the value of a would be:
![a = \frac{b}{60}](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7Bb%7D%7B60%7D)
We need to find ![\frac{4b}{a}](https://tex.z-dn.net/?f=%5Cfrac%7B4b%7D%7Ba%7D)
Therefore, we have to put the either values of a and b in the specified equation:
Hence,
![\frac{4b}{a} = \frac{4(a * 60)}{a}](https://tex.z-dn.net/?f=%5Cfrac%7B4b%7D%7Ba%7D%20%20%3D%20%5Cfrac%7B4%28a%20%2A%2060%29%7D%7Ba%7D)
We have only put the value of one variable to evaluate or to make it variable free
![\frac{4b}{a} = \frac{240a}{a}](https://tex.z-dn.net/?f=%5Cfrac%7B4b%7D%7Ba%7D%20%20%3D%20%5Cfrac%7B240a%7D%7Ba%7D)
or
![\frac{4b}{a} = 240](https://tex.z-dn.net/?f=%5Cfrac%7B4b%7D%7Ba%7D%20%20%3D%20240)
Therefore, the value of 4b/a is 240.
Answer:
m BC = 100
Step-by-step explanation:
Since the angle is at the center, the arc has the same measurement as the angle
m BC = 100
