So you need to know that
1. 360 degrees=1 full rotation
2. internal angle of a pentagon
3. internal angle of a square
so we know that
internal pentagon angle+internal pentagon angle+internal angle of square+x=360
internal angle of pentagon=54
internal angle of square=90
so now we have
54+54+90+x=360
198+x=360
subtract 198 from boths ides
x=162
answer is x=162 degrees
