Answer 1

Abcd is a square

cpd is an equilateral triangle

then angle Apb =180 degree

Answer 2

Answer:

APB=150

Step-by-step explanation:

HERE IN TRIANGLE DCP

DP=DC=CP

And

DC=AD

so, AD=DP

now in triangle APD

AP=AD=75

As, ADP=90-60=30

same goes for triangle BPC

Now, 75+75+60+APB=360

APB=150
