I don't understand how to do these 3 questions please help me if you can.

Step-by-step explanation:

a)  90 degrees -  lines that are tangent to a circle form right angles

b) 67 degrees - triangles have an area of 180 degrees. Since point p is tangent it is 90 so you would do x+23+90 =180 and solve (23 being the given angle).

c) 43 degrees - similarily to question b) point p is tangent and triangles are a sum of 180 degrees you would do x+47+90 = 180 and solve

I hope this makes sense i tried my best to explain.
