Answer:
<h2>Triangle A B C. Angle B is a right angle.</h2>
Step-by-step explanation:
A dilation with a scale factor of 2 represents a transformation where the preimage ABC would be smaller and the triangle A'B'C' would be twice bigger. That means, the pre-image will be inside the image.
Also, as you can observe in the image, angle B is a right angle. Triangle A'B'C' has B' as a right angle too.
Additionally, line segment B'C' is twice bigger than line segment BC, because the preimage is smaller.
Therefore, the only right answer is the first one.

Answer:
17 is 25% of 68
Step-by-step explanation:
All angles on a triangle add up to 180. If it's a right triangle it would be set up like this: 90+3x-4=6x-5=180. You would subtract 90 from 180 and get 90 left. 3x-4+6x-5=90. Then you would add 5 and 4 to 90.....3x+6x=99. Then you add 3x and 6x then you would be left with 9x=99. Divide 99 by 9 and you get x=11.
