Answer:
The answer is A.
Step-by-step explanation:
○Lets Angle 1 and the angle with in a linear pair.
○Now we have 53+42+Angle x = 180° (Angle sum property of triangle)
= 53+42+x= 180
= 95+x= 180
= x= 180-95
= x= 85°
○Now that we found x, we can take angel x and angel 1 in linear pair again.
= Angelx + Angel 1= 180° (Linear Pair)
= 85 + Angel 1= 180°
= Angel 1= 180-85
= Angel 1= 95°
Therefore, option A is correct.
