Answer:
35.8 deg
Step-by-step explanation:
a/sin A = b/sin B
24/sin x = 39/sin 71.8
sin x = (24 * sin 71.8)/39
sin x = 0.584598
x = sin^-1 0.584598
x = 35.8 deg

Needing to find the circumference of a circle you you find that you need to use the equation C=2 π R 
C= 28.26 
this is how much fence they would need around the garden approximately.
