Given: BC = 10 inches AC = inches m∠CBD = 60° m∠CAD = 90°

darkknight:

Is there a diagram associated with this problem

darkknight:

@dangermanger I think your problem is incompletely worded too.

darkknight:

We can't help you without a diagram. Use attach file feature and screenshot

dangermanger:

one moment- im struggling to upload it

ramen:

are we tryna find ac?

dangermanger:

dangermanger:

dangermanger:

I had to draw it out

darkknight:

But what are we trying to find?

dangermanger:

the area of the shaded region

ramen:

ok that makes a lot more sense

dangermanger:

sorry im new to this! still learning how to work everything- i redrew the figure to hopefully make it easier

ramen:

its fine thanks though

darkknight:

Alright. So I'll just redraw this to make it easier on myself and you. Also you can use the draw feature

dangermanger:

thank you!!

ramen:

so we have an oval in middle right?

dangermanger:

correct!

darkknight:

Well it is not an oval Oval: An oval is a curve resembling a squashed circle but this shape has points, so it won't be an oval, im pretty sure. Unless @dangermanger drew it wrong

ramen:

yea actually dark is right, the points meet up nvm

darkknight:

But the shape isn't an oval

darkknight:

What math is this?

dangermanger:

geometry

ramen:

do you have notes?

dangermanger:

dangermanger:

ramen:

from what i see in the image, c to b and c to a are the radius of the circles

dangermanger:

dangermanger:

those are my notes on this subject- I have never taken a geometry class and I need to teach myself now with the quarantine happening.. my teacher is doing her best to help but she doesnt really know either considering she is an english teacher

dangermanger:

dangermanger:

ok- those are all my notes on the subject.

ramen:

im a bid hindered... can you try plugging in the numbers from this problem into the formula from your notes?

dangermanger:

yes!

ramen:

I'll let someone who knows more of this type of problem take over

ramen:

but i hope i helped a little...

dangermanger:

the diagram with all the given information:

dangermanger:

I need to find the area of the "shaded" region

imqwerty:

Post your attempt so that we know where you're stuck.
