I believe it is C because the Associative property states that no matter how you use your parenthesis the answer will be the same <span />
Take 654 and divide it by 218.
654/218=3
Another way that I solve this is look at 8 and see what number times 8 have 4 at the end. 3x8=24. Check and see. 218x3=654.

Answer:
(a) 78
Step-by-step explanation:
The sum of arcs of a circle is 360°. The measure of θ is the average of the measures of arcs BD and AC.
AC +AD +BD +100 = 360
(2BD) +(2BD) + BD = 260 . . . . use the given relation for AC, AD; subtract 100
BD = 52 . . . . . . . . . . . . . . . . . divide by 5
θ = (AC +BD)/2 = (2(52) +52)/2 = 52 +26
θ = 78 . . . . degrees
