Check the picture below.
we know B is the midpoint of AC, and we know ED is 4 units, since AD is a total of 8, then AE must also be 4 units, meaning point E is the midpoint of AD.
since E is the midpoint of AD and B is the midpoint of AC, then EB is the midsegment of the triangle, and is parallel to the base DC.
∡ABE = 60°
∡AEB = 90°
Answer:
line 2
Step-by-step explanation:
on line 2 the two minuses at the end turn into a + (where the -2 is there should be a +2) because - x - = +
Answer:

Step-by-step explanation:
Since the statement is false, there are no solutions to the system of equations. This also indicates that the lines are parallel.
It is Bioelectrical impedance machine, these devices are used to measure the percentage of fat on your body so it is B
Answer:
And solving we got:
Step-by-step explanation:
For this case we can define the following notation:
represent the width
And we want a maximum error of 0.0003 so we can set up the following equation:
And solving we got:
