#a = sqrt407#

Use the Pythagorean Theorem, if you're talking about right triangles:

#a^2 + b^2 = c^2#

We must find #a# given #b# and #c#. We know that #b# is #13# and #c# is #24#, so we can plug those values into the formula.

#a^2 + (13)^2 = (24^2)#

#a^2 + 169 = 576#

#a^2 = 407#

#a = sqrt407#
