HackerRank Find Angle MBC solution in python | python question solution

 is a right triangle,  at .
Therefore, .

Point  is the midpoint of hypotenuse .

You are given the lengths  and .
Your task is to find  (angle , as shown in the figure) in degrees.

The first line contains the length of side .
The second line contains the length of side .

• Lengths  and  are natural numbers.

Output  in degrees.

Note: Round the angle to the nearest integer.

Examples:
If angle is 56.5000001°, then output 57°.
If angle is 56.5000000°, then output 57°.
If angle is 56.4999999°, then output 56°.
