Hi there! The fourth answer is correct.
In the picture we have to deal with facts:
1. The angle of 45°
2. The length of the opposite side
3. The length of the adjacent side.
Since we have to use the opposite and the adjacent side, we have to use the tangent of the angle. In a formula:
Filling in this formula, brings us to the following answer.

Answer:
- Disitributive property.
- Addition property of equality.
Step-by-step explanation:
The complete exercise is attached.
For this exercise you need to remember the following properties:
1. The Distributive property states that:
2. The Addition property of equality states that:
Then, given the equation:
You can identify that the first property John used was the Distributive property:
After combining like terms, you can identify that the next property he applied was the Addition property of equality, adding to both sides of the equation:
