We are given a right triangle so that we can use the Pythagorean Theorem to solve for the measurement of the other leg. We use the expression written as:
c² = a² + b²
where c is the hypotenuse, a and b the other legs.
153² = 72² +b²
18225 = b²
b = 135 cm
Hope this answers the question. Have a nice day.
