Question

Find the value of x.
A. 1.1
B. 6.6
C. 8.8
D. 5.5

Answer 1

B. 6.6

Explanation:

AC is a midsegment of the trapezoid DFBE.

The formula of a midsegment of trapezoid is:

`m=(a+b)/(2)`

a, b - bases of a triangle

We have

a = x, b = 4.4, m = 5.5

Substitute:

`5.5=(x+4.4)/(2)` multiply both sides by 2

`11=x+4.4` subtract 4.4 from both sides

`6.6=x\to x=6.6`
