Answer:
The factor form is 
Step-by-step explanation:
When it is required to factor the expression given in the problem, we have to first find a common term or terms, which will be found by either grouping the like terms or the splitting of the terms.
Now the expression that is given here is:

Now, here we will take:

Thus we will get:

Now we will do the middle term split as follows:

Substituting back
, we will have:

Hence, the required factor form of the given expression will be:

The coefficient will be 5.
Answer:
The measure of arc AC length is 90 degrees
Step-by-step explanation:
Here, we want to get the measure of the arc AC
From what we have, the angle at the middle facing this arc is a right angle
A right angle is of the size 90. degrees
with respect to the diagram, the angle at the center is equal to the measure of the arc facing it
Thus, we can conclude here in this case that the measure of arc AC is 90 degrees
