You just need to work out the length of the circumference of the circle and equate it to the length of the arc of the sector in terms of theta(the angle of the sector) and then solve for theta. making touch screen monitor

"WebThe angle of the diameter (180 °) is the central angle that subtends the arc represented by half the circumference. Tracing a triangle with the diameter being one of the sides, we would automatically form an inscribed angle that also subtends the same arc as the angle of the diameter. Thus, that inscribed angle would be half of 180 ° (90 ... " - Geometry arc and angle rules
