Answer:
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.

Answer:
10 feet.
Step-by-step explanation:
The formula for the area of a triangle is A=1/2bh
where A is the area B is the base and H is the height.
The area is 60 and the base is 12 so the formula will become
60=1/2*12*h
60=6*h
by dividing both ends by 6
10=h
the height of the triangle is 10.

X^2+y^2-6x+4y+18=0
x^2-6x+y^2+4y+18=0
x^2-6x+9+y^2+4y+4 =-18+9+4
(x-3)^2+(y+2)^2=-5
-5 is the minimum value of the given circle
Answer:
\/226 is te exact form
Step-by-step
/(x2-x1)^2 +(y2-y1)^2
/((-8)-7)^2 + ((-5)-(-4))^2
/226
Decimal form is 15.03329637
So 15.03
The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.
<h3>Why should the second arc be centered at C?</h3>
The second arc should be centered at C because as it crosses passing through Line C, it is seen that it was not touching or intersecting AB and so one can say that it is parallel to it.
Looking at the other lines, we will see that they are all touching AB and are not running parallel to it.
Hence, The option that needs to be corrected in this construction of a line parallel to line AB passing through C is C: the second arc should be centered at C.
