When you have a right triangle, you can use the Pythagorean Theorem to find the missing side length. (this can only be used for RIGHT triangles)
Pythagorean Theorem:
a² + b² = c² [c is the hypotenuse, or the longest line]
Since you know b = 8 and c = √73, plug it into the equation
a² + 8² = (√73)²
a² + 64 = 73
a² = 9
a = √9
a = 3
