WebSi 1 plus si 2. Right, that larger angle is si 1 plus si 2. Once again, this subtends this entire arc right here, and it has a diameter as one of the cords that defines this huge angle. So this is going to be 1/2 of the central angle that subtends the same arc. We're just using what we've already shown in this video. WebAngle = (11 × 360°)/ (2 × 22/7 × 7) Angle = 90°. Therefore, the angle of the arc is 90°. Example 2: Find the missing angle x in the diagram below. Solution: We need to find the value of x. One angle is given as 80°. By inscribed angle theorem we know that the central angle = 2 × inscribed angle. x = 2 × 80.
