start with the equilateral triangle

I already did

but im confused with the external tangent stuff

can you draw a diagram

and show me how it is

[muted oxide]

the circle is tangent to a side of the triangle and outside the triangle

ohhh ok

thanks

and what is it asking for

can you help me solve it

I don't know how to start

[muted oxide]

i would suggest reading the rest of the problem to find out

is it asking for the highlighted?

yes

or this?

is the diagram like the picture one above

[muted oxide]

this is more accurate

how do I go from there

what is the answer

try to find that region as the difference of two areas

which 2 areas

what is the answer tho

[muted oxide]

i’m not allowed to tell you the answer

but I don't know which 2 areas

[muted oxide]

i’ll give you a hint: the problem with finding the area of this region is that it has a curved side

try to find the area of a shape that has the same curved side, but is easy to find
