Find the missing angle.<br> SHOW YOUR WORK!
igomit [66]

Answer:

120º

Step-by-step explanation:

All of the interior angles of a triangle have to add up to 180º, so the missing interior angle is 60 degrees once you add 24 and 96 and subtract the sum of 120 from 180.

As for the missing angle, it's supplementary with the interior one that was originally unknown. Subtract 60 from 180, and that will give you 120º.
