Answers:
- The missing angle is 41 degrees.
- 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.
