Robert is completing construction of a square inscribed in a circle, as shown below. What should be the next step in his construction?

A circle is drawn with diameter of segment AB.

Construct a perpendicular bisector to line AB.
Place his compass on the radius and draw two arcs above and below line AB.
Make another circle from point B with the same radius as his original circle.
Draw a line parallel to line AB that touches the circle at point A.

i think it is c, not positive though

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

the correct answer is $7.38
