Answer:

Take the information given and create an equation that add up to 360.

Step-by-step explanation:

You might assume the smallest angle to be the given 55, so that would make the third term 120+55. The fourth angle is unknown, x

The equation sets up as

55+65+(55+120)+x = 360

Add all the numbers to get 295.

295+x=360

Subtract 360-295 = x

x=65

The four angles are 55°,65°,175° and 65°

I hope this answers your question!
