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

The complement of an acute angle (<90º) A is the angle 90º-A
In this case:
the complement of an angle that measures 37º is 90º-37º=53º
Answer: B.53º
6 consecutive even numbers
First x
Second x+2
Third x+4
Fourth x+6
Fifth x+8
Sixth x+10
126=x+x+2+x+4+x+6+x+8+x+10
126=6x+30
Subtract 30 from both sides
96=6x
Divide both sides by 6
x=16
Fourth x+6=16+6=22
