In circle t, ∠ptq ≅ ∠rts.

what is the measure of pq?

24°
33°
48°
66°

answer

66°

explanation

the angles ∠ptq and ∠rts are directly opposite hence equal.

pr and qs are diameters of the circle hence equal. this been the case, line pq and rs are equal.

the conclusion of the is the arcs pq and rs are equal.

rs = pq = 66°

answer: c

(2, -4)

goes 7 to the

(9, 4)

easy

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
