Find the length x in each triangle. Express your answer in simplified radical form.
long side is 12
x is the straight side
8 is the bottom of the triangle

= 144 + 64
= 208
Yip, but it's only wrong because the long side =shortest*middle. so
.: minus 64 on both sides
now square root both sides

simplify the radical
80-->2*2*2*2*5, or 16(5); and 16 is a perfect square of 4. therefore,
== Otherwise, you would have been completely right.
