- Question
O and O' are the center of the two circles with radii 7cm and 9cm respectively. The distance between the centers is 20cm. If PQ be the transverse common tangent to the circles, which cuts OO' at X, what is the length of O'X in cm ?
Options- A. 10
- B. 6
- C. 35/4
- D. 45/4
- Correct Answer
- 45/4
ExplanationAs clear from the figure itself, triangle OQX and triangle O'PX are similar.
So,
OQ/O'P = OX/O'X
=> OX = (7/9)xO'X
And since, OX + O'X = 20
=> (7/9)xO'X + O'X = 20
=> O'X = 45/4
