Answer:
Measurements are:
BA= 21
AC= 41
BC= 32
Step-by-step explanation:
the sum of all of the sides is 94 so therefore 2a + 1 + 3a + 2 + 5a - 9 = 94
from there you can combine like terms which would give you: 10a - 6 = 94
then you solve for a. a = 10, so if you replace a with 10 in every equation you get the measurements of the sides:
2(10) + 1 = 21
3(10) + 2 = 32
5(10) - 9 = 41
