Question

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

Answer 1

import Foundation

func calculateRightTriangleAngle(opposite: Double, hypotenuse: Double) -> Double {
    let angleSin = opposite / hypotenuse
    let angleRadians = asin(angleSin)
    let angleDegrees = angleRadians * 180.0 / Double.pi
    
    return angleDegrees
}

let opposite: Double = 2.5
let hypotenuse: Double = 5.0

let rightTriangleAngle = calculateRightTriangleAngle(opposite: opposite, hypotenuse: hypotenuse)

print(String(format: "Right Triangle Angle = %.2f", rightTriangleAngle))



/*
run:
  
Right Triangle Angle = 30.00
  
*/
