u have picture?
what do u mean by vertex in a circle?
yeah..a picture might help
i'm trying to find a picture pls w8 for couple of more mis
I be back, the angles depen
angle b/w A and B
between A and B?
A and B are the points on a circle, u can find the central angle of the arecAB
just 90 degrees lol
why make it complicated
well, the figure is drawn roughly, may not b perpendicular
how to find the central angle
u need more info, the radius and the length of arc
arc length=radius * central angle
A B is 90 degree then the central angle is the same
yeh, thats prob it , im not paying much attention tonight
the angle on the circle is 1/2 angles in center
radius is 50 mm and length is 78.5 mm but i'm getting 1.57 deg
the answer you get is in radians
if you are using l =r theta
pi radians = 180 degrees , therefore 1 radian = 180 / pi degrees
which works out as 90degrees exactly
so I was right from the start :P
what do u mean how come, I was right
right if the lines are perpendicular,
well, it turns out they are :P
yes, the seem to be :)
but actually the qs is to find the angle b/w A n B
angle is 90 , done
angle is 90 , done
conditiionally done ;)
