The length of RP is 6.1 units.
The tangent is defined as a line touching circles or an ellipse at only one point.
given:
QR is a tangent, the length of RQ = 5.3
radius of the circle, QP = 3 units
As, tangent to a circle is perpendicular to the radius
So, ∠PQR = 90°
Now in ∆ PQR,
RP² = RQ² + QP²
RP² = 5.3² + 3²
RP = √[5.3² + 3²]
RP = √[28.09 + 9]
RP = √[37.09]
RP = 6.0901
RP = 6.1 units
Hence, the length of the RP is 6.1 units
