Final answer:
The problem requires solving for angle A in a triangle with specific side lengths and an angle given, but lacks sufficient information to determine the exact angle without additional data or assumptions.
Step-by-step explanation:
The student is asking for help in solving for angle A in a triangle where angle C is 47°, and sides a and b are given with lengths 8 and 5, respectively. This appears to be a problem related to triangles, possibly requiring the use of the Law of Sines or Law of Cosines. However, without additional information such as whether the triangle is right-angled, or the relationship between the sides and angles (i.e., which angle is opposite which side), we cannot provide a definitive solution to the problem as presented.
It's important to note that if this were a right-angled triangle and angle C is the right angle, then angle A would be easily found by subtracting angle C from 90°, as the sum of angles in a triangle equals 180°. Nevertheless, since the type of triangle isn't specified and the sum of the given angle C (47°) and the two remaining angles must be 180°, we can only deduce that angle A must be less than 133° (180° - 47°).
