Answer:
Step-by-step explanation:
angle 2 is 43 degree because angle 2 and 43 are vertically opposite angle and vertically opposite angles are always equal.
angle 1 is 137 degree because the sum of two angles in a straight line is always 180 degree.so
43+angle 1=180 degree
angle 1=180-43 degree
angle 3 is 137 degree because the relation between between angle 3 and 137 degree is vertically opposite angles and vertically opposite angles are always equal.
vertically opposite angles=e and c
complementary angle=b and c
supplementary angle=e and d
10: angle 2 is 43 because it is vertical to angle 43. Angle 1 is 137 (180-43) and angle 3 is also 137 because 1 and 3 are vertical angles.
11: a) e and c
B) c and b
C) c and d
D) c and b, c and d, d and e, e and a, a and b
E) c is 30, b is 60, a is 90, e is 30, d is 150
