Question

In finger, seg AB congruent seg AD
seg BC congruent seg DB angle BCD equal to 65 degree.Find the values of x,y,z and p​

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.
