Answer:
1624 units²
Step-by-step explanation:
See attachment for the figure
As, ∠EAB = ∠CFD
and ∠ABE = ∠FCD
We can say that by AA congruency, ΔCFD is similar to ΔBAE
Therefore, BA / EB = CF / DC
BA x DC = EB x CF (since EB = CF
)
BA x DC = EB²
28 x 58 = EB² => area of square BCFE
area of square BCFE = 1624 units²
Therefore, the area of square BCFE is 1624 units²

Answer:
The temperature on the 5th day was of -9ºC.
Step-by-step explanation:
Mean of a data-set
The mean of a data-set is the sum of all values in the data-set divided by the number of values.
The mean temperature for the first 4 days in January was 1°C.
This means that during the first 4 days, the sum of the temperatures was 4*1 = 4ºC.
The mean temperature for the first 5 days in January was -1°C.
First 4 days: Sum of 4º
5th day: Temperature of x.
The mean is -1, so:
The temperature on the 5th day was of -9ºC.
