Can some1 pls explain to me how to do katrina is building a deck. she cuts 3 lengths of wood from a 72-inch board. the first length is . 3. 4. inches. the second length is . 1. 4. inches. and the third length is . 1. 4. inches. how much of the original board remains after katrina makes her cuts?

Rewriting the question, the given lengths that were cut from the board were 30 3/4 inches, 12 1/4 inches, and 16 1/4 inches. To obtain the remaining length of the board, all of the measurements cut are to be added and subtracted from 72 inches. This is shown below:

30 3/4 + 12 1/4 + 16 1/4 = 237/4 = 59.25 inches.

Remaining length of board = 72 - 59.25 = 12.75 inches.

Therefore, there will be 12.75 inches remaining of the board.

D:Length side LM over length of side MN equals length of side XY over length of side XZ.

Step-by-step explanation:

We are given that two triangles LMN and XYZ are similar.

We have to find the not necessarily  true information  about given triangles.

We know that when two triangles are similar then their corresponding angles are congruent and the ratio of corresponding sides of two triangles are equal.

Therefore,

But , is not necessarily true.

Hence, option D is  true option.

Answer : D:Length side LM over length of side MN equals length of side XY over length of side XZ.
