Answer:
A) TA
Step-by-step explanation:
A radius goes from the center of a circle to the outside edge.  
RP connects two points on the outside edge of the circle without going through the center.  This is not a radius.
TR connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.
GP connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.
TA connects the center of the circle to the outside edge.  This is a radius.

Step-by-step explanation:
a)
82+OCE=90°{ tangent}
0CE=8°
OCE=OEC (base angle of isosceles triangle r equal}
8+8+a=180°(sum of angle of triangle)
a=180-16
a=164°
b)d+BEC=180°
BEC=122°
BEO=BEC-OEC
b=114°
