Use the pythagorean theorem:
EF² +DF²=DE²
EF²=18²-12²=180
EF=√180
E is the answer.
Answer: 92
Step-by-step explanation:
The symbol is ">" (not "≥") so the line is dashed, not solid.
A solid line is used to indicate the boundary line is part of the solution, as it is in the "or equal to" case.

Answer:
Dot plot
Step-by-step explanation:
In a dot plot, the temperature of a day is represented by 1 dot. There are 30 dots on the box plot shown in the attachment that was made by Tia.
This dot plot display makes it easier to find how many days had a temperature that is higher than 15°.
Thus, from the dot plot, we have:
2 dots representing 2 days having a temperature of 16°C each
2 days also have daily temperature of 17°C
2 days have temperature of 18°C as well, and
1 day has temperature of 19° C.
Therefore, the number of days that had a temperature above 15°C is 7 days.
