Look a the figure find the length of em?

because 10 and the opposite side are the same you guess and check the 2x+4. (3*2)+4=10

x=3

6x+2

(6*3)+2=20

the length EM is C, 20

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
