Consider the circles c1, centered at (0,0) with radius 2, and c2, centered at (4,0) with radius 1. inversion in either circle is an improper isometry of the half-plane, and so (inversion in c1) followed by (inversion in c2) is a direct isometry, i. e., a fractional linear transformation. write this flt in the form (az+b)/(cz+d); determine whether it is a rotation, a parabolic translation, or a hyperbolic translation; and find its fixed points (in the half-plane, or at infinity).

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.
