Here are the pictures to my working... didn't know how to explain without pictures
Hope this helps though :)
Answer ≈ 71.57o
+37146 See image below:
angle z + angle apq + 45 = 180 degree straight line
tan z = x / (1/2 x) = 2
arctan(2) = z = 63.434
63.434 + APQ + 45 = 180
APQ = 71.565 degrees
+1694 ∠APB = arctan(2/1) = 63.43494882º
∠CPQ = 45º
∠APQ = 180 - (∠APB + ∠CPQ) = 71.56505118º
sin(∠APQ) = 0.948683298
