Answer:
15 degrees.
Step-by-step explanation:
First, count from -34.44 degrees to 0 degrees which is (0 - 34.44)=34.44 counts
Next, you determine how many more counts you need to reach the 49.44 degrees ; that would be 49.44 - 34.44 = 15
Therefore, the Antarticas highest recorded temperature was 15 degrees.
