Well, 360 is a full circle so 180 is half a circle so, 180-19=161
161 is your answer. Hope this helped!
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.
It would be 7x10^-2
That number would be rounded to 0.07
