Question 1:

"Match" the letters

DE are the last two letters of BCDE

The last two letters of OPQR is QR

DE is congruent to QR

Question 2:

Blank 3: Reflexive property (shared side)

Blank 4: SSS congruence of triangles (We have 3 sets of congruent sides)

Question 3:

I'm guessing those two numbers are 7.

Since both are 7, AB and AE are congruent.

We know that all the other sides are congruent because it is given.

We also know that there is a congruent angle in each triangle.

Thus, the two triangles are congruent by SAS or SSS.

(Note: I couldn't prove this without the two "7"s because there is no such thing as SSA congruence)

Have an awesome day! :)

**Answer:**

Everyone in my household has a computer either for school or work. The youngest needs a computer so she can stay busy and not bother me at all.

We all have different reasons to have one so we all need one.

**Answer:**

x=70

**Step-by-step explanation:**

To solve this problem, you set up the equation 45+(2x-5)=180

Next, subtract 45 from 180 to get the equation 2x-5=135

After that, add 5 to 135 to get 2x=140

Divide 140 by 2 to get X=70

5•6=30

30-5/5=29

(5/5=1)

29+2=31

Answer: 31
