Answer:
Dale is not correct (see the explanation)
Step-by-step explanation:
step 1
Divide 1/4 by 3 ( Dale and two friends)
[tex](1/4)/3=\frac{1}{12}[/tex]
step 2
we know that
The complete circle (cake) have a central angle of 360 degrees
Divide 360 degrees by 12
[tex]\frac{360^o}{12}= 30^o[/tex]
That means----> Each slice of 1/12 has an angle measure of 30 degrees
therefore
Dale is not correct
