To find a, we will use the Pythagoras theorem,

adjacent² + opposite² = hypotenuse²

From the diagram, opposite = 5 adjacent = a hypotenuse =13

substitute the values into the formula and evaluate

a² + 5² = 13²

a² + 25 =169

subtract 25 from both-side of the equation

a² = 169 - 25

a² =144

Take the square root of both-side

a = 12
