3 1/2
Step-by-step explanation:
5--2=7
6-4=2
7/2= 3 1/2
The answer is four because there's one line that is placed on the origin which makes it no solution because there's not supposed to be a line on the origin and number 1 is a solution because there are neither lines plotted on the origin and has parallel lines
A) 4
∠14 & ∠12
∠11 & ∠13
∠10 & ∠8
∠7 & ∠9
vertical angles are angles directly opposite of each other and are of the same measurement.
hope this helps
