I believe the correct answer C
Answer:
y=3x-1 (replace x with 7 )
Step-by-step explanation:
y=3 (7)-1
y= 21-1
y= 20
note: multiply 3 with seven and minus 1 the answer is y so y=20
X is equal to 16. This is because angle Z is congruent to angle X, which means that angle Y and angle W are congruent so if you use the calculation
x + 3 = 2x - 13 you will get that x is 16.

Vertical angle means opposite angles.
- It states that If two lines intersect each other, then the vertically opposite angles are equal.
For eg :- In this diagram,


Linear pair means to form 180°.
- It states that the two axioms above together is called the Linear Pair Axiom.
- If the sum of two adjacent angles is 180°, if non-common arms of the angles form a line.
