Question

- In the figure, C is the centre of the circle.
Seg QT is a diameter CT = 13, CP = 5, find
the length of chord RS.​

Answer 1

Answer:

RP = PS

RS=24cm

Step-by-step explanation:

1. RS=PS
2. In ∆RPC
3. (RC)²=(PC)²+(RP)²
4. (13)²=(5)²+(RP)²
5. 169=25+(RP)²
6. 169-25=(RP)²
7. (RP)²=144
8. RP=12
9. RS=RP+PS
10. RS=12+12=24
