the required ans is 3√b+b/3b
ANSWER:
50.88
STEP BY STEP
First you would do 64 x .25 which is 16
Then you would take the 16 away from 64 so it would be 48
Then you have to add the tax so it would 48 x .06 = 2.88
Finally you would add the 2.88 to 48 which is 50 .88
12) Angle ACD= Angle ABC+ Angle CAB ====> You MAY end here
That is, Angle ACD= 132+21
Angle ACD= 153
13) Angle ABC+ Angle BAC= Angle ACD====> You MAY end here
That is, Angle ABC +16=143
-16= -16
Angle ABC=127
1/4 because 0.25 is the same thing as 25/100. 25/100 simplified is 1/4
