Question

In the figure, O is the center, PT and PR are tangents, and

mZTOR = 150°. If OR = 6 cm, then what is the measure of
ZTPR?
a. 210°
b. 30°
c. 105°
d. 15°

Answer 1

b. 30°

Explanation:

In quadrilateral OTPR, angles O and P are supplementary.

angle P = 180° -angle O = 180° -150°

angle P = 30° . . . . matches choice B
