7) alternate interior angle, Angle measure = 71°
8) alternate interior angle, Angle measure = 90°
Step-by-step explanation:
Using an illustration:
7) The angle type is alternate interior angle
Alternate interior angle angles are equal.
Hence, the angle measure which is represented with question mark = 71°
8) The angle type is alternate interior angle
Alternate interior angle angles are equal.
The square in red represents 90°
Hence, the angle measure which is represented with question mark is 90°
