Answer: Top Left, Middle Left, and Bottom Right
Step-by-step explanation:
Let's go over through each answer choices. We will go down the first column then the second.
Adjacent angles are two angles that have a common side and a common vertex.
This means that for answer choice 1, this is correct. Angle 1 and the 50 degree angle are adjacent angles; they have a common side and a vertex that is surrounding them.
To find the angle for 1, we need to subtract the angle of the line, which is 180, by the other adjacent angle to get 130 degrees. This approach is exactly what answer choice 2 is saying and therefore is correct.
Angle 2 is easily able to decipher, so answer choice 3 is not correct (we will get to this later).
Vertical angles are angles opposite each other when two lines cross. Think of two pencils in a thin x shape. The smaller angles are vertical while the bigger angles are the duo vertical angles as well.
Using this information, Angle 1 and 50 degree angle is not vertical. it does not make sense.
To find angle 2, we need to take into account that a triangle is 180 degrees, and since we know the 50 and 45 degrees, we need to subtract that from 180 to find the actual value, 85 degrees. This deems the second to last answer wrong and the last as right.
Hope this helped!
