for a right triangle with legs legnth a and b and hypotnuse (longes side) legnth c a²+b²=c²
depends which one is the hyppotonuse if we assume that bc is the hypotnuse, then 7²+b²=10² 49+b²=100 minus 49 b²=51 sqrt both sides the missing side is √51
if we assume that the hypotonuse is ab then 7²+10²=c² 49+100=c² 149=c² sqrt both sides √149=c
if bc is the hypotonuse, then ab is √51 if ab is the hypotonuse, then ab is √149
