Ill give brainiest - please help ASAP

WITH THE WORK THO PLEASE?

13.

<S=½(arc TQ- arc TR)=½(143-71)=36°

14.

<E=½(arc DG- arc DF)=½(169-59)=55°

15.

arc PR=180-62=118°{sum of opposite angle of quadrilateral in circle is supplementary)

16.

arc TR =180-47=133°

again

arc T?R=360-133=227°

17.

62+38x+4=180

38x=180-66

x=114/38

x=3

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

they aren't great and cause destruction, idk man
