Circle A has center of (2,8) and a radius of 2 and circle B has a center of (5,4) and a radius of 10. What steps will help show that circle A is similar to circle B A.) Translate circle A using the rule (x-3, y+4) B.) Rotate circle A 270° about the center C.) Reflect circle A over the line x=1 D.) Dilate circle A by a scale factor of 5.

d. is the correct answer

step-by-step explanation:

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

nope

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
