Answer:
length of second base = 11 units
Explanation:
Assume that the second base is x
The mid-segment in a trapezoid is calculated as follows:
mid-segment = (first base + second base) / 2
We have:
mid-segment = 19
first base = 27
second base = x
Substitute in the equation and solve for x as follows:
mid-segment = (first base + second base) / 2
19 = (27+x) / 2
19*2 = 27+x
38 = 27+x
x = 38 - 27
x = 11 units
Hope this helps :)
