:: Set up the equation 52 + h² = 132
:: Square 5 and 13 to get 25+ h² = 169
:: Subtract 25 from both sides to get h² = 144
:: Take the square root of both sides h = 12 cm
:: Square 5 and 13 to get 25+ h² = 169
:: Subtract 25 from both sides to get h² = 144
:: Take the square root of both sides h = 12 cm
