Let the centre of the circle be P, then <CBP = <BCP = 1/2(180 - 112) = 1/2(68) = 34°
<ABC = 90 - 34 = 56°
y = 56 + 14 = 70°

Option C is correct

a(b + c) = ab + ac  demonstrates the distributive property

Step-by-step explanation:

Distributive property states that:

Let x, y and z are number, then;

A.

This does not follow distributive property.

B.

ba = ab

This does not follow distributive property.

C.

a(b + c) = ab + ac

This follow the distributive property.

D.

ac – ab = -ab + ac

This does not follow distributive property.
