Question

A quadrilateral PQRS is inscribed in a circle, as shown below.


What is the measure of arc PQR? (1 point)

Select one:
a. 210°
b. 255°
c. 105°
d. 75°

Answer 1

hint :
Q + S = 180
solve for S

then the measure of arc PQR = 2 * S

Answer 2

If a quadrilateral is inscribed in a circle, the opposite angles add up to 180.

So angles PQR + PSR = 180

Also measure of arc PQR will be double the angle PSR.

Answer 3

a?

Answer 4

yes.

Answer 5

ok thank you
