a) DE=DC cos they’re both radii DC=CE cos they’re also both radii therefore DEC is equilateral
b) p=2x30/360 x 2x32xpi +32

#

The line D-E and the line C-E are both same as they both are radii

#

So the triangle CE and DE are also the same as they're both radii

#

So, if all the sides are the same, then it's an equilateral triangle

#

You then have the find the arc length of both

#

The angle will be 30

#

So 30/360

#

Multiply it by 2

#

So (2 x 30) /360 X 2x32xpi

#

32 is the circumference

#

You multiply it by 2 as there's two arc length

#

Then add the length of A-B
