Problem

Ray OBOB stands on straight line ACAC, creating two adjacent angles ∠AOB\angle AOB and ∠BOC\angle BOC. Their measures are given by (7x−23)∘(7x - 23)^{\circ} and (5x+3)∘(5x + 3)^{\circ} respectively. Respond to the following points: (i) Explain why ∠AOB\angle AOB and ∠BOC\angle BOC are supplementary. (ii) Form an equation in xx using this relationship. (iii) Solve the equation to find the value of xx. (iv) Calculate the exact measure of each angle and state whether any of them is a right angle.
