Answer: B and C
Step-by-step explanation: For A, vertical angles can be complimentary or supplementary. For D, vertical angles can sometimes be acute but not always.
The original number was: " 14 " .
____________________________________
a + 5 = b ;
b * 7 = 133 .
______________________________________________
What is: "a" ?
______________________________________________
133 / 7 = 19 = b ;
a + 5 = b = 19 ;
a + 5 = 19 ;
Subtract "5" from each side of the equation;
to isolate "a" on one side of the equation; and to solve for "a" ;
_______________________________________________
a + 5 − 5 = 19 − 5 ;
to get:
________________________________________________
a = 14 .
________________________________________________
Let us check our answer:
Start with "14" ;
Add "5" : "14 + 5 = 19 " .
______________________
then multiply by "7" : "19 * 7"
__________________________
and the result is: 133 ?
__________________________
19 * 7 = ? 133 ? Yes!
