Introduction

In geometry, a triangle is a polygon with three sides and three angles. The sum of the interior angles of a triangle is always 180 degrees. In this article, we will explore how to calculate the third angle of a triangle given the other two angles.

Understanding the Problem

The problem of calculating the third angle of a triangle is a fundamental concept in geometry. It is a simple yet important concept that has numerous applications in various fields such as physics, engineering, and computer science.

The Formula

The formula to calculate the third angle of a triangle is given by:

180 - (a + b)

where a and b are the two given angles.

Breaking Down the Formula

Let's break down the formula to understand how it works.

a + b: This is the sum of the two given angles.
180 - (a + b): This is the third angle of the triangle, which is calculated by subtracting the sum of the two given angles from 180 degrees.

Implementing the Formula in JavaScript

The formula can be implemented in JavaScript using the following code:

// 3. Calculating the Third Angle of a Triangle
function calculateTriangleAngle(a, b) {
    return 180 - (a + b);
}

let a = 80, b = 65;
console.log("Triangle Angle: " + calculateTriangleAngle(a, b));

How the Code Works

Let's walk through how the code works.

function calculateTriangleAngle(a, b): This defines a function called calculateTriangleAngle that takes two arguments a and b.
return 180 - (a + b): This is the formula to calculate the third angle of the triangle. It subtracts the sum of the two given angles from 180 degrees.
let a = 80, b = 65;: This defines two variables a and b and assigns them the values 80 and 65 respectively.
console.log("Triangle Angle: " + calculateTriangleAngle(a, b)): This logs the result of the function call to the console.

Example Use Cases

The code can be used in various scenarios such as:

Calculating the third angle of a triangle given the other two angles.
