An isosceles triangle has it's vertex on a circle. If /PQ/=26cm, /QR/=26cm and /PR/=20cm. Calculate the height of the triangle and the radius of the circle to the nearest whole number

Answer 1

Do you mean it has all of its vertices on the circle? If so, then
Let M be the midpoint of PR.
Now you have two 2*(5-12-13) right triangles.
The center of the circle lies 2/3 of the way from Q to M, where the medians meet.

Answer 2

Yes
