Answer:

  • x = 19
  • x = 34
  • x = 39

Step-by-step explanation:

1. A right angle has a measure of 90°. The whole is the sum of the parts.

  (2x +3)° +49° = 90°

  2x +52 = 90 . . . . . . . . divide by °, collect terms

  2x = 38 . . . . . . . . . . . . subtract 52

  x = 19 . . . . . . . . divide by 2

__

2. A linear pair measures 180°. The whole is the sum of the parts.

  (x -5)° +151° = 180°

  x +146 = 180 . . . . . . . divide by °, collect terms

  x = 34 . . . . . . . . .subtract 146

__

3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.

  64° +(3x -1)° = 180°

  3x +63 = 180 . . . . . . . divide by °, collect terms

  3x = 117 . . . . . . . . subtract 63

  x = 39 . . . . . divide by 3
