Answer:

x = 76

Explanation:

All angles must add up to 360 degrees. So, we add the angles we already have.

104 + 123 + 57 + x= 360 we will solve for x

284 + x = 360 add all known values on the left

x = 76 we subtract 284 from both sides to isolate x

To check our answer, we add all values

104 + 123 + 57 + (76) = 360 This is correct. :)
