The smaller triangle is the image of the larger triangle after a dilation. The center of the dilation is (4,2).

Answer:
-1/3
Step-by-step explanation:
Take the ratio of the corresponding sides to get the scale factor so for this equation let's use the hypotenuse.
The length of the hypotenuse of the larger triangle is 12 units and the smaller triangle's hypotenuse is 4 so 4/12 is the scale factor.
However 4/12 can be simplified down to 1/3.
Since the smaller triangle has been flipped upside down the scale factor is negative so the final answer is -1/3

Answer:
A
Step-by-step explanation:
<em>-7 -5 / 4 -2 / -12/2 </em>
<em>-12/2 = -6 </em>
<em>Slope: -6x </em>
<em>5 = 2(-6) + b</em>
<em>5 = -12 + b </em>
<em>-12 + 17 = 5 </em>
<em>Slope intercept Form: y = -6x + 17</em>
You will get x as 56 and angle ABC as 51°
