Question

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

Answer 1

use std::f64::consts::PI;

fn main() {
    let opposite: f64 = 2.5;
    let hypotenuse: f64 = 5.0;

    let angle_sin: f64 = opposite / hypotenuse;
    let angle_radians: f64 = angle_sin.asin();
    let right_triangle_angle: f64 = angle_radians * 180.0 / PI;

    println!("Right Triangle Angle = {:.2}", right_triangle_angle);
}



/*
run:

Right Triangle Angle = 30.00
