Pre-image abcd is dilated to be
image a'b'c'd'. the origin is the center of dilation
what scale factor is used to create the dilation?
enter your answer in the box.

Scale factor is 5

Focus on point A. It is located at (1,2)

Then note the coordinates of point A' which is (5,10)

The jump from (1,2) to (5,10) has us multiply the coordinates by 5

The same can be said going from B to B', from C to C', and from D to D'.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
