Answer 1

9514 1404 393

Answer:

  32°

Step-by-step explanation:

Let x represent the measure of the third angle. Then the second angle is 4x and the total of all angles is ...

  20 +4x +x = 180

  5x = 160 . . . . . . . . . . subtract 20

  x = 32 . . . . . . . . . . . divide by 5

The third angle measures 32°.
