A line meets the co-ordinate axes in A & B. A circle is circumscribed about the triangle OAB. If d1 and d2 are the distances of the tangent to the circle at the origin O from the points A and B respectively, the diameter of the circle is:
- \(\frac{2 \mathrm{~d}_{1}+\mathrm{d}_{2}}{2}\)
- \(\frac{\mathrm{d}_{1}+2 \mathrm{~d}_{2}}{2}\)
- d1 + d2
- \(\frac{\mathrm{d}_{1} \mathrm{~d}_{2}}{\mathrm{~d}_{1}+\mathrm{d}_{2}}\)
Answer
(C) d 1 + d 2
