Answer:
135°
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 720

Answer:
A, D
Step-by-step explanation:
When solving for x, we want to get all x terms on one side and all non-x terms on the other side. To make it so that x is by itself, we need to get rid of -3. We can do this by adding 3 to both sides, which demonstrates the addition property of equality. This property states that if you add a quantity to one side of an equation, you must add the same quantity to the other side as well.
