We have given that area of the sector is $\frac{7}{20}$ of the area of the circle. Therefore, area of the sector = $\frac{7}{20}$xx area of the circle $\therefore$ $\theta$/360xxpir^2=$\frac{7}{20}$xxpir^2 Now we will simplify the equation as below, $\theta$/360=$\frac{7}{20}$ Now we will multiply both sides of the equation by 360, $\therefore$ $\theta$=$\frac{7}{20}$xx360 Therefore, sector angle is $126^\circ$
