If PA and PB are tangents drawn from an external point P to a circle with centre O such that $$\angle$$APB = 70$$^\circ$$, then         $$\angle$$OAB is equal to:

In $$\triangle$$ABC, E and D are points on sides AB and AC, respectively, such that $$\angle$$ABC = $$\angle$$ADE. If AE = 6 cm, AD = 4 cm

and EB = 4 cm, then the length of DC is:

The value of $$\frac{4}{5} \div 3 \frac{1}{4}$$ of $$\frac{8}{13} - \frac{\frac{1}{5} - \frac{1}{8}}{\frac{1}{5} + \frac{1}{8}} \times 5 \frac{1}{5} + \frac{5}{6}$$ is
