The median of the trapezoid is the average of the bases. If we draw the trapezoid that is being described in this item, we will deduce that AB and DC are the bases and EF is given to be the median.
For this item,
EF = (AB + CD) / 2
Part A:
EF = (15 + 11) / 2 = 13
Part B:
AB = 2EF - CD
AB = (2)(14) - 10 = 18
Part C:
18 = ((5n - 9) + (2n + 3))/2
18 = (7n - 6) / 2
n = 6
Part D:
2y + 4 = ((5y + 2) + (-3y + 8))/2
y = 1
EF = 2(1) + 4 = 6
AB = (5(1) + 2 = 7
AB = -3(1) + 8 = 5
Answer:
Induction
Step-by-step explanation:
Induction is "the creation of a voltage difference across a conductive material (such as a coil of wire) by exposing it to a changing magnetic field."
Answer:
x = 8
Step-by-step explanation:
These are corresponding so they are congruent.
Your equation is: 14x-4=12x+12
x=8
Answer:
74
Step-by-step explanation:
Since J is the midpoint, that just means that both CT and JT are going to be the same length. With that information we can create an equation and solve for x.
5x - 3 = 2x + 21
5x = 2x + 24
3x =24
x = 8
Now to find the length of CT, we will add both equations to find the total length.
5x - 3 + 2x + 21
5(8) - 3 + 2(8) + 21
40 - 3 + 16 + 21
37 + 16 + 21
53 + 21
74
Best of Luck!
