Find Angle MBC in python - HackerRank solution

Solution for hackerRank problem Nested lists in python

Problem :

ABC is a right triangle, 90^o at B.

Therefore <ABC = 90^o .

Point M is the midpoint of hypotenuse AC.

You are given the lengths AB and BC.

Your task is to find <MBC (angle 0^o as shown in the figure) in degrees.

Input Format

The first line contains the length of side AB .

The second line contains the length of side BC.

Constraints

0 < AB <= 100

0 < BC <= 100

Lengths AB and BC are natural numbers.

Output Format

Output <MBC 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°.

0^o < θ^o < 90^o.

Sample Input

10

10

Sample Output

45°

Procedure

1. Start.

2. Import math module.

3. Get the length of the sides.

4. Find the AB/BC.

5. AB/BC = tan θ.

6. θ = tan^-1 (AB/BC).

7. Round the angle to integer.

8. Print the angle in degrees.

9. End.

Code

import math

s1 = int(input())

s2 = int(input())

s = s1/s2

angle = round(math.degrees(math.atan(s)),0)

angle = int(angle)

print(str(angle)+chr(176))
