Question

1. ABCD is a trapezoid with midsegment EF. If AB = 12 and CD = 24, what is the length of EF?

Answer 1

Answer:

5

Step-by-step explanation:

Answer 2

For all of these answers, the equation used was (AB + CD)/2 = EF

1.12+24=36    36/2=18
2. 21 + 35 = 56    56/2 = 28
3. (7 + EF)/2 = 9 
    multiply by 2
   7 + EF = 18
   subtract 7
EF = 11

4. (AB + 32)/2 = 22
Multiply by 2
AB + 32 = 44
Subract 32
AB = 12

5. Average
