If the lines are parrellel, then the measure of angle CBA is the measure of DAB - 180°. Just think of them as supplementary angles.
In other words, 180-125=55
So the measure of angle CBA is 55°
A[1] = 14 . . . . . . . . . defines the first term
a[n+1] = a[n] -4 . . . says each term is 4 less than the one before it
Answer:
6
Step-by-step explanation:
