Answer:
tangent QP = 8 cm
Step-by-step explanation:
The length of the tangent can be find by using Pythagoras property
First draw radius on tangent in such a way that it falls at 90°.
This problem can be solve using Pythagoras Theorem.
This theorem is used for Right angle triangle. In right-angle triangle if one of the sides is unknown then we can find it by using the formula:
(Hypotenuse)² = (Base)² + (Perpendicular)²
Firstly take the ΔOPQ, We have
OP = 10, OQ = 6 and QP = ?
⇒ (OP)² = (OQ)² + (QP)²
⇒ 100 = 36 + (QP)²
⇒ (QP)² = 100 - 36 = 64
⇒ QP = 8
Thus, tangent QP = 8 cm
