10-4 =6
14x10= 140
50+49= 99
49x10=490
Side b is adjacent to the 30° angle so use cosine to solve. (soh cah toa)
cos(30°) = b/12
12*cos(30°) = b
cos(30°) is √(3)/2
12*(√(3)/2 ) = b
6√(3) = b
3 goes in the box

Answer:
Jane is 14 
Step-by-step explanation:
The age of each person increases by a fractional amount. In order to find Jane's age, you will need to start with Ari's age and then add the additional fractional amounts. In order to add with fractions, the denominators must be the same. In the case of Glen, you can figure his age out first:
12
+ 1 
5 and 6 have a common denominator of 30, so multiply the numerator and denominator by the same factor and than add:
12
= 12
+ 1
or 1
= 13 
Taking Glen's age and adding the additional amount for Jane:
13
+ 1
or 1
=14
