Answer:
Explanation:
Alright. First for this question we have to figure out what we're finding. This type of angle is called Exterior Consecutive Angles. They are in the same line and it is outside we can understand with Ext with exit.
Second. We need to observe if it has a acute and a obtuse angle. If they do you add if they don't then they are equal to each other. Clearly we see they are obtuse and acute so we add them. (7x - 17 + 7x + 1 = 180)
Third. Combine like terms. 14x - 16 = 180
Continuing it we do 180 + 16 = 196
Now its => 14x = 196
14x / 14 and 196 / 14
= x = 14
Therefore x is 14. Have a great day.
