Question

If you know length of OE and length of BE to be 1.22 and 1.22 how do you get the length of OB?

Answer 1

It's 1 but I don't get how they got 1

Answer 2

lool omg

Answer 3

never mind I see it it's just labelled

Answer 4

Well you can see that B is at (0,0,1) and since O is at the origin, B is directly above O. Therefore, B can only be 1 unit away from O.

Answer 5

Actually how d oyo uget BE?

Answer 6

they did sqrt(1^2+.5^2+.5^2). is that because we have three axis?

Answer 7

yes. its just the distance formula for 3d points. Distance = sqrt((x2-x1)^2 + (y2-y1)^2 +(z2-z1)^2)

Answer 8

alright awesome thank you

Answer 9

no problem
