Answer:
[tex]\text{Only R}[/tex]
Step-by-step explanation:
[tex]\text{i. }\angle\text{P}=\angle\text{R}=74^\circ\text{ because they are base angles of isosceles triangle.}\\\\\mathrm{ii.\ \angle P+\angle Q+\angle R=180^\circ}\text{ [Sum of angles of triangle is 180}^\circ.]\\\mathrm{or,\ 74^\circ+74^\circ+\angle Q=180^\circ}\\\mathrm{or, \angle Q=32^\circ}[/tex]
