The area of trapezoids abec, abfd, and $abfc are 133, 140, and 161 square feet, respectively. quadrilateral abed is a rectangle. the length of segment de is 8 feet. what is the length of segment cf

The length of segment CF is 15

Step-by-step explanation:

Let = ABEC = 133

Let  = ABFD = 140

Let A = ABFC = 161

Let = A = 8 AD

Let x = CF

+  = A +

133  + 140 = 161 +  

 = 133 + 140 - 161

 = 122                                = 8AD

8AD = 122

AD=

AD=14

A= × AD

161 = ×14

161 = (8 + x )×7

23 = 8 + x

x = 23 - 8

x= 15

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
