Correct Answer: 9.9

Solution : $\frac{\sqrt{3}+\sqrt{2}}{\sqrt{3}-\sqrt{2}}$
Rationalizing the denominator,
= $\frac{(\sqrt{3}+\sqrt{2})^2}{(\sqrt{3}-\sqrt{2})(\sqrt{3}+\sqrt{2})}$
= $\frac{(3+2+2\sqrt{6})}{(3-2)}$
= $5+2\sqrt6$
= 5 + (2 × 2.45)
= 5 + 4.9
= 9.9
Hence, the correct answer is 9.9.

Correct Answer: 30

Solution :
Given:
OB = 10 cm, OA = 17 cm, BC = 12 cm
Drawing a perpendicular from centre O on BC cuts BC in M.
BM = $\frac{1}{2}×$BC = $\frac{1}{2}×$12= 6 cm
From $\triangle$OBM,
OB² = OM² + BM²
$\therefore$ OM =
