C is the independent variable because it is all by itself.
Answer:
D) 6.4
Step-by-step explanation:
The Angle Bisector Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.
This means that:
18/9.6 = 12/x
Solving for x:
x = 12*9.6/18
x = 6.4
Assuming line J is parallel to k.
∠5 = ∠1 = 34° (Corresponding angles)
Answer: 34°
