Answer:
3rd graph.
Step-by-step explanation:
Roots of the equation are where the graph crosses the x axis. So the bottom left (3rd) graph is correct.
Answer:
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
