Answer: 225°
Explanation:
The correct option is D)
Refer Figure
Given:
ABCD is a square
ABP is an equilateral triangle
AB=BP=BC (△ABP is equilateral and AB and BC belong to a square, hence all are equal)
∠ABC=∠ABP+∠PBC=60°+∠PBC
90°−60°=∠PBC
∠PBC=30°
In △BPC
BP=BC
∠BPC=∠BCP= 2
180−∠PBC
( angles opposite to equal sides of a triangle are equal)
∠APC=∠APB+∠BPC=(60+75)°=135°
Hence, Reflex ∠APC=(360−135)°=225°
