Answer:
b = 90°
Step-by-step explanation:
Angles a, b, c total 180°, and angles a and c are complementary, meaning they total 90°. The measure of angle b is ...
b = 180° -90°
b = 90°
__
All of the angle measures are ...
a = 90° -c = 90° -56° = 34°
b = 180° -90° = 90°
c = given = 56°
d = given = 124°
e = c = 56°
