Look at my picture, what’s the missing statement in step 4?

Step-by-step explanation:

∠ACE=∠ BCD (reflexive property )

It is common to both the angles or both the angles represent the same angle.

We have to prove two triangles are similar.

Here we show two angles of different triangles are equal.

Hence similar by AA  

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
