Answer:
X = 25 degrees
Definitions:
Vertical: Opposite angles/angles that share a common side.
Adjacent: Congruent meaning same measure.
Explanation:
This equation would be vertical because they are opposite from eachother:
Our equation would look like this:
75 = 4x - 25
Then add 75 and 25 to get 100:
75 + 25 = 100
Now our equation would look like this:
100 = 4x
Lastly, divide 100 with 4:
100 ÷ 4 = 100
Side note: 25 x 4 = 100
Your answer would be x = 25 degrees.
Hope this helps!
