Geometry: an overhead view of a revolving door is shown....

[ambygurl182]

I need help big time with my geometry help and I need it tonight. This is the first problem.
1. an overhead view of a revoving door is shown in the accompanying diagram. Each panel is 1.5m. the question is what is the approximate width of D, The opening from B to C? on the diagram its a circle with a X through it and each section has 1.5 m

 

[skeeter]

what kind of triangle is formed by one section of the X and a line segment drawn from B to C?

what do you know about the side length relationships for this "special" triangle?

 

[ambygurl182]

It is an X inside the circle and it has that there is four sides inside the circle and each are 1.5

Hello, ambygurl182!

We still have to guess what the diagram looks like . . .

Skeeter asked the right questions . . . Have you found any answers?

The question is: what is the approximate width of the opening from B to C?

\(\displaystyle \Delta OBC\text{ is a 45-45 right triangle with legs: }OB \,=\,OC \,=\,1.5\)
