Angle Q is represented by (2x−5)∘. Answer the following questions:
a. (i) Write, in terms of x, the expression for the angle that completes angle Q to a right angle.
b. (ii) If the angle obtained in part (i) measures (3x+1)∘, form an equation in x and solve it.
c. (iii) Hence, find the exact measures of angle Q and its corresponding completing angle.
