Answer:
√122
Step-by-step explanation:
Find the length of the third side. If necessary, write in simplest radical form. square root of 58 8
let the given sides be;
Hypotenuse = x
Adjacent = √58
Opposite = 8
Using pythagoras theorem;
hyp^2 = opp^2 + adj^2
x^2 = (√58)^2+8^2
x^2 = 58 + 64
x^2 = 122
x = √122
Hence the length of the unknown side is √122
