Question

How to calculate an angle of a right triangle given opposite and hypotenuse in C

Answer 1

#include <stdio.h>
#include <math.h>

int main(void) {
    float opposite = 2.5;
    float hypotenuse = 5;

    float angle_sin = opposite / hypotenuse;
    float right_triangle_angle = asin(angle_sin) * 180 / M_PI;

    printf("Right Triangle Angle = %f", right_triangle_angle);
}




/*
run:

Right Triangle Angle = 30.000000
