Answer:

The angle P is
P = 26^o

Explanation:

From the question we are told that

The angle BD is
BD = 154^o

Now looking at the diagram we can deduce that angle
B \r CD = 180 ^o

Now looking at line AD we see that it is tangent to the circle this implies that line CD is perpendicular to line AD

So we can also deduce that


B \r C A + D \r C A = 180

=>
D \r C A = 180 - 154

=>
D \r C A = 26^o

Now total angle in a triangle is 180 so


C\r DA + D\r A C + A \r C D = 180^o

Now
D \r A C = 90^o

So


D \r AC = 180 - (90 + 26)

=>
P = D \r AC = 26^o
