Angle??

by KICKGMATASS123 » Fri Jul 24, 2009 10:38 am
Can someone tell me how u find the attached angle??

I would think it's 90 degrees.. since the angle of diagonal of square and it's length is 45 and since there are 2 45 angles combined..

However, OA is C

Thanks much!

The answer is 60 degrees. Calculate each diagnol on the cube and you will see they are the same length, i.e sqrt(2)x. Since they are the same length, the triangle is equilateral hence 60 degrees on each angle.
