d) 20

Step-by-step explanation:

To find possible side lengths use the triangle inequality theorem. The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. So for the measurements 6, 11, 20 to make a triangle 6+11 must equal at least 20, which isn't true. Therefore, 20 cannot be a measurement for this triangle.

i could probably can you me with a question of mine?

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
