Alex drew a circle with right triangle PRQ inscribed in it, as shown below: The figure shows a circle with points P, Q, and R on it forming an inscribed triangle. Side PQ is a chord through the center an

If the measure of arc QR is 80°, what is the measure of angle PQR? (6 points)

Select one:
a. 50°
b. 40°
c. 80°
d. 70°

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
