options
a) 15°
b) 75°
c) 105°
d) 165°

Option C). 105°

Step-by-step explanation:

From the figure we can see a cyclic quadrilateral QRST

To find the measure of <RST

From the figure we can see that, angle RST is an obtuse angle.

The measure of angle RST is nearer to a right angle that is nearer to 90°

From the options we get the measure of angle RST = 105°
