Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
10.54 cm^2. You just have to find area of the square then area of the circle. Subtract the area of the circle from the square to get the answer
