-14 + x
Is the correct answer
Dilation, as both images are similar, but they are no longer the same size (either smaller or larger).
Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.
The answer is D because the opposite sides are equal to each other, so you have 2 of each measurement. Also, midsegments divide each side of the bigger triangle in half. So 2 (1/2AC + 1/2AB)= the perimeter of the quadrilateral but the 2 in front will cancel out both halves, so we are left with AC+AB (OPTION D)

Answer:
x ≈ 8.0
y ≈ 6.0
Step-by-step explanation:
For x, the relevant trig relation is ..
Sin = Opposite/Hypotenuse
sin(53°) = x/10
x = 10·sin(53°)
x ≈ 8.0
__
The value of y can be found in the same way using the 37° angle, or the cosine function can be used.
y = 10·sin(37°) ≈ 6.0
y = 10·cos(53°) ≈ 6.0
_____
<em>Additional comment</em>
This question only asks for the value of x. We expect there may be some versions of this question in which the value of y is requested, or in which the positions of x and y are switched. Please compare your question carefully before you copy the answer.

You may notice this is a 3-4-5 triangle with a scale factor of 2.
