Does it not give you the degree of the central angle?
well, it's a circle...i'm not sure. i will set the problem as my profile picture lol
You can attach File... located at the bottom of where you post instead...
oh okay :D
What are you trying to find?
Is this a unit circle?
Look at the angle made up from Arc AB. There is a vertical angle equal to that angle made from Arc ED.... Do you see that those two are equal?
they are both 50?
Yes so the arc EDC that you are trying to find is a total of 90 degrees. The arc length is found by multiplying the degrees (90) times the radius. I don't know what your radius is...
it doesn't give me a radius...hmmm
i could give you the multiple choice answers?
45pi 45 5pi/2 5pi
sorry, i didn't find the pi symbol. and the 3rd one is a fraction
i have an attachment in it
oh awesome! thanks :D
5 * pi/2
oh, wait sorry, 90 isn't an option
again; without any knowledge of the radius, there is no way to solve an arclength for this; so its most likely an angle
jonknet, yours is an option
convert degrees to radians
yeah amistre64 it is difficult
yes; radian measures....its good to know what the real question is :)
r=5. theta = 90pi/180 = pi/2. multiply out.
r = 5? wheres that at?
oh thank you so much!!!
AD = 10
i see no 10 lol
It's not in the picture. Check Momo's response a few up.
I almost missed it too lol
you guys are awesome! thank you so very much!!
