P= 16 over 3 this is the straight forward answer
The dilation is a scale factor of 2, that is:
C'D' = 2(CD)
the length of CD is given by:
CD = √( (a - 2a)^2 + (b - b)^2 )
<span>CD = √(a^2) = a
</span>
hence the new segment is 2a long.
Answer:
The measure of the angle ACB is 59°.
Step-by-step explanation:
Let be 
the location of the center of circle and 
is the radius of the figure, the triangles ACD and BCD are isosceles triangles, since 
. And the measure of the angle C associated with each triangle are, respectively:
Triangle ACD
Triangle BCD
Lastly, the measure of the angle ACB is:
The measure of the angle ACB is 59°.
ANSWER: B = 10/C
You have to isolate the variable by dividing each side by factors that don’t contain the variable
