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
