4 0

Answer:

53 mm

Step-by-step explanation:

Perimeter is the sum of the lengths of all its sides.

Let the length of the unknown side be x mm.

123= 25 +45 +x

x= 123 -25 -45

x= 53

Thus, the unknown side is 53 mm.

2. angle ABE = angle MNP <br><br> Write another valid congruency statement:​
Free_Kalibri [48]

Given:

\Delta ABE\cong \Delta MNP

To find:

The congruent angles and sides, then find the another valid congruency statement.

Solution:

We have,

\Delta ABE\cong \Delta MNP

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

Using CPCTC, we get

Angles:

\angle A\cong \angle M

\angle B\cong \angle N

\angle E\cong \angle P

Sides:

AB\cong MN

BE\cong NP

AE\cong MP

The another congruent statement is \Delta BEA\cong \Delta NPM.

Therefore, the required table is

Angles                                              Sides

\angle A\cong \angle M                                        AB\cong MN

\angle B\cong \angle N                                        BE\cong NP

\angle E\cong \angle P                                        AE\cong MP

The another congruent statement is \Delta BEA\cong \Delta NPM.

Write the equality for the graph
Veronika [31]

≥ the graph would be going to your right

≤ the graph would be going to your left

Both cases assume x is on the left side of the inequality.

If the circle is open < or > will be used.

If the circle is shaded in then use ≤ or ≥

If the circle is open, then x<2 would indicate that the ray is going left (which it is) and 2 is not included.

Answer: x < 2
