Question

3. m(arc PS) = 95°, ROQ = 80°, find m(arc RQ).​

Answer 1

Answer:

ZCAB = 90°

Step-by-step explanation:

It is given that line AB is tangent to the

circle at A.

:: ZCAB = 90°

(Tangent at any point

of a circle is perpendicular to the radius

throught the point of contact)

Thus, the measure of ZCAB is 90°.
