please check the correct answer

Answer 2

Answer:

100⁰

Step-by-step explanation:

If we join PO and prove SSS conguence between the triangles, we will find that the angles are equal. so it is 100⁰

I tried explaining this step wise, when I used the triangles names, it didn't accept. it was saying rude. I erased everything and am saying it in a simpler way.

hope you understand.
