Challenge 3

Here, you were asked to make a function to solve for c in a^2 + b^2 = c^2. After solving for c, you get c = sqrt(a^2 + b^2) or:

// The data type used doesn't matter too much, but it makes sense for it to be a floating-point number of sorts.
fn pythagoreanTheorem(float a, float b) {
    float c = a * a + b * b;
    c **= 0.5;
    return c;
}
