Answer:
(a) 2S, 1A
Explanation:
A triangle is completely specified when all three sides and all three angles are known. This triangle shows the measure of 1 side, so 2 sides are missing (2S). It shows the measures of angle Q and P, so angle N is missing (1A).
The missing information is 2 sides and 1 angle: 2S, 1A.
