Question

In Figure 1. AB is a tangent to the circle with centre at O from an
external point A. If OA = 6 cm and OB = 33 cm, then the length of the
tangent is​

Answer 1

Step-by-step explanation:

ANSWER:

(1) It is given that line AB is tangent to the circle at A.

∴ ∠CAB = 90º (Tangent at any point of a circle is perpendicular to the radius throught the point of contact)

Thus, the measure of ∠CAB is 90º.
