Question

3. PR = 25 cm. With P and Ras centres, two circles of radii 12 cm and
cm are drawn. A third circle with centre Q and radius x cm is
drawn touching the first two circles externally and anglePQR = 90°.
Find the radius x.


the answer from answer sheet is 18m

please give me the correct answer and I will mark your answer as brainlist ​

Answer 1

The given are:

PR = 25cm

the radius of circle with centre P is: 12cm

the radius of circle with centre R is: 7cm

And, ∠ PQR = 90°

Now, PQ = x + 12 cm

QR = x + 7 cm

By using the Pythagoras theorem, we get:

Ans: x = 8cm. ( Kindly refer to the above Attachments )

Answer 2

Check the above answer and mark it as whether it's a Brainliest or not.

As value of x = 8cm ( not 18m )
