# Length of remaining two sides of a Triangle from a given side and its adjacent angles

Given the length of a side a of a triangle and its adjacent angles B and C, the task is to find the remaining two sides of the triangle.

Input: a = 5, B = 62.2, C = 33.5
Output: 4.44, 2.77
Explanation
The remaining two sides of the triangle are b = 4.44488228556699 and c = 2.7733977979419038
Input: a = 12, B = 60, C = 30
Output: 10.39, 5.99
Explanation
The remaining two sides of the triangle are b = 10.392304845413264 and c = 5.999999999999999

Approach:

1. The remaining angle can be calculated by the angle sum theorem in a triangle:
2. The other two sides of triangle can be computed using sine formula:

Below is the implementation of the above approach:
