Answers:

  1. The missing angle is 41 degrees.
  2. The missing angle is 51 degrees.

==================================

Work Shown for Problem 1

The interior angles of any triangle always add to 180 degrees.

x+112+27 = 180

x+139 = 180

x = 180-139

x = 41 is the answer to problem 1.

-------------

Work Shown for Problem 2

x+62+67 = 180

x+129 = 180

x = 180-129

x = 51 is the answer to problem 2.
