This is a, this is b and let us suppose this is i0, this is x, this is y, this is b.
00:15
So if we resolve this we can assume this as o and let us suppose this is ob.
00:23
So this is bb, this is 120 degree and this is 60 degree so that makes 180 degree.
00:33
This is also 60 degree and this is also 60 degree and let us suppose this component is va, this is small v as bb is given as 1 .2 meter per second, theta is equals to 120 degrees.
00:50
This is one more diagram in which we have this was alpha, this was theta and this was alpha, this is o, this is b, this is a, this is b, this is also b, this is our bb.
01:10
2 alpha plus theta is equals to 180 degree, angles and property of a triangle.
01:15
So we have 2 alpha is equals to 60 degree or alpha is equals to 60 by 2 that is 30 degree.
01:24
Angle aib, ai0b, it is an equilateral triangle.
01:33
So in that equilateral triangle we can say the x side is equal to y side, x side is equals to y side and that is given as b...
