Step-by-step explanation:

1) ∠P = 14

∠O = x

∠Q = 90   {tangent and radius meet at 90 in the point of contact}

ΔOPQ,

Sum of all angles = 180

∠P +∠O +∠Q = 180

14 + x + 90 = 180

104 +x = 180

x = 180 - 104

x = 76

2)  AB = 9

AO = 10.5

Using Pythagorean theorem

AB² + OB² = OA²

9² +  r² = 10.5²

81 + r² = 110.25

r² = 110.25 - 81

r² = 29.25

r = √29.25

r = 5.4
