Answer:

See below.

Step-by-step explanation:

1a)

Angles:

  • 48, 90, 90, a.

Add:

  • 48 + 90
  • = 138 + 90
  • = 228

Subtract:

  • 360 - 228
  • = 132.

Angle a: 132.

1b)

To get angle h above 180°, We need to add h + 164:

  • h + 164
  • = 110 + 164
  • = 274.

h = 110.

This is how to get h over 180°.
