Let's talk about the choices
◯ ∠4 and ∠5 . . . . . . . . these are complementary angles whose sum is 90°
◯ ∠7 and ∠9 . . . . . . . . these are vertical angles, equal to each other
◯ ∠2 and ∠3 . . . . . . . . these are supplementary angles that together form a straight line. They are a linear pair.
◯ ∠1 and ∠2 . . . . . . . . these are "adjacent" angles in the quadrilateral that also includes ∠9 and ∠10.
The appropriate choice is ...
◉ ∠2 and ∠3
Given the arithmetic sequence is given by:
an=4-3(n-1)
writing the above into a straight line form we get:
an=4+3-3n
an=-3n+4
this a straight line equation with a negative slope, thus the domain will be:
(-∞,∞)

Answer:
BC is a minor arc
Step-by-step explanation:
Just as an extra piece of information that can help us:
Knowing that the diameter splits a circle into halfs, it's degree measure is half of the degree measure of the whole circle: 360/2 = 180 degrees.
This means that diameter AC consists of a 180 degree measure, helping us in the sense that:
mBC + mBA = mAC
mBC + 70 = 180
mBC = 180 - 70
mBC = 110 degrees
Now the mBC to the mBEC is 110: 250 such that we know arc BC is smaller in size as degree measure is proportional to circumference length. Knowing it is smaller in length, BC is thus a minor arc.
