Geometry math question no guessing and show work you

length of two sides are 7 and 10

We have this rule:

sum of two sides of triangle > third side

let us check for given sides

7+2>10, 9>10 ( false)

7+1>10, 8>10 (false)

7+4>10, 11 >10 ( true)

so option C , third side = 4 is correct

step-by-step explanation:

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
