Answer:
mCEA = 90ᴼ, as CEA forms a right angle, and by definition, right angles measure 90ᴼ.
The angle CEF is classified as a straight angle as it combines two right angles (CEA and AEF), equating to 180ᴼ altogether. Straight lines are defined to measure 180ᴼ.
AEF is determined to be a right angle as CEA is already a right angle, and since CEF is a straight line, AEF must also be a right angle.
From a distance of 300 feet, a car approaches you at a speed of 48 feet per second. The distance d (in feet) of the car from you after t seconds can be described by the equation d=|300−48t|. At what moments does the car find itself 60 feet away from you?
The average is also known as the mean, calculated as the sum of values divided by the total number of data points.
Values are h, j, and k
The total data count is 3
The sum of the values is represented as h + j + k
Thus, the mean is [h + j + k] / 3
=> Answer: option c. [h+j+k] over 3
The response is A
I hope this information is useful.
