Answer:

  b = 90°

Step-by-step explanation:

Angles a, b, c form a linear angle, so their sum is 180°. This means ...

  a + b + c = 180°

  b = 180° -(a +c)

Angles 'a' and 'c' are complementary, so their sum is 90°.

  b = 180° -90°

  b = 90°

__

We can also find the measures of the other angles in this geometry.

  a = 90° -c = 90° -56° = 34°

  e = c = 56° . . . . . . . . . vertical angles

In summary, ...

  a = 34°, b = 90°, c = 56°, d = 124°, e = 56°
