Answer:
6
Step-by-step explanation:
0.33. 1/3= 0.33
d= (6 x 523)
Pi
0.33
d= (3138) divide by pi first
0.33
d= 999.36
d= 9.77
Using the calculator it is 27.47 round off to 27.5
Since AK = KD, then the triangle ABD is isosceles,
Then BD = AB. Denote AB by x and AK by y.
Then,
2x+4y=24 (the perimeter)
cos 60=y/x.
From the second equation we get
Plug in the first equation we get:
We deduce that
