Question

Find the value of x.

a. 6.6
b. 5.5
c. 8.8
d. 1.1

Answer 1

Here AC is the median of the isoceles trapezoid DEBF. Formula to find the median of a isoceles trapezoid is:

AC=
`(EB+DF)/(2)`

Next step is to plug in the values from the diagram in the abov formula. So,

`5.5=(x+4.4)/(2)`

`5.5*2=(x+4.4)/(2) *2` Multiply by 2 to each sides.

11= x+4.4 Simplify.

11-4.4= x Subtract 4.4 from each sides.

So, x=6.6
