Hi, from the question given that, consider the given figure and from this figure we need to find the center distance y.
00:09
So center distance y is the thing we need to find here.
00:16
And also given that three volts are equally spaced.
00:21
So the distance between each holds is equal.
00:30
And let us consider the center point.
00:33
So i have draw this here.
00:35
So from the center like this and let it be o and this is a and this is b and the center point is c.
00:56
Since 3 volts were equally spaced on a circle with diameter d is equal to 295 mm.
01:06
Then the angle made by any 2 oles with the center, so angle made by any 2 oles, so angle made by any 2 oles, with the center is 120 degree since the old circle as 360 divided by 3 which is equal to 120 degree.
01:32
Thus the angle included between the lines oa and oc is 120 degree.
01:43
Therefore angle a .oc is equal to 60 degree.
01:49
So, since this is 120, therefore this part is alone 60 and this is also 60.
01:58
So here we need to calculate the distance y, which is twice of ac.
02:05
So first find the distance ac by using the sign formula...
