I'll give brainliest if you help me!! Find the value of x. If needed round to the nearest tenth (one decimal place)

x = 8.7

Step-by-step explanation:

The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:

8 = 12

We can simplify this down to

2 = 3

Now that we have this proportion we can apply it to Lines AE and EC

2(13) = 3x

26 = 3x

8.67 = x

Therefore x is equal to 8.67 (or 8.7 rounded)

Check:

8/12 = 0.6667

8.6667/13 = 0.6667

Since both are the same, the answer is correct.

I hope this helps!!

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
