RQ = 6; RS = 6 ; these are radius
The triangle formed is right triangle. ∠RQP = 90°
QP = 8 ; this is the long leg.
RQ = 6; this is the short leg
RP = ? is the hypotenuse
a² + b² = c²
8² + 6² = c²
64 + 36 = c²
100 = c²
10 = c
The hypotenuse is 10, but RS is part of the hypotenuse, it has a measure of 6.
6 + x = 10
x = 10 - 6
x = 4 length of SP
