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=$\frac{EB+DF}{2}$

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

$5.5=\frac{x+4.4}{2}$

$5.5*2=\frac{x+4.4}{2} *2$ 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
