Oof...

Oh ok thanks for the link!

S = (n - 2) x 180

S/180 = n - 2

Its pretty obvious from here...

Because the triangle is a right triangle, and the sides are equal, you can tell that:

If the leg(s) = x

x*sqrt(2)=hypotenuse

I think it is very easy to solve from here.

Wow thank you so much! You did more than needed which is incredible. Thank you!

You want to use the intersecting chord theorem. This means that:

60^2 = (48)(48+x)

It should be very simple from here!

Woah! Thank you so much! I understand what drawing those lines was meant to do! Thanks!

No, but I think the clue helped! I still don't really understand what to do next though...

Thank you everyone! I really needed some help on the question, and you helped me so much. Thank you!
