Answer:

The exact answer would be:


√(39) +
√(7) +
√(46) an approximate answer to the nearest whole number would be 7

Explanation:

To find the missing side we would use the Pythagorean Theorem.


a^(2) +
b^(2) =
c^(2)


√(7) ^(2) +
b^(2) =
√(46) ^(2)

7 +
b^(2) = 46 Subtract 7 from both sides


b^(2) = 39


\sqrt{b^(2) } =
√(39)

b =
√(39)

The perimeter, the distance around the triangle, is
√(39) +
√(7) +
√(46)
