Answer:
angle 2 = 90° {corresponding angles}
angle 7 + angle 5 = 180° {linear pair}
or, angle 7 + 100° = 180° {angle 5 is corresponding to 100°}
so, angle 7 = 80°

Answer:
-1
Step-by-step explanation:
If i = √-1, then i^2 = -1.
M<1+ m<2 = 90
-2x + 54 + 8x + 18 = 90
6x + 72 = 90
6x = 90 - 72
6x = 18
x = 3
