<h2>Hello!</h2>

The answer is: C. 16 m.

<h2>Why?</h2>

The figure is a right triangle, it means that we can solve it by using the Pythagorean theorem which states that, the largest side of a rectangle (hypotenuse) is equal to the sum of the other two side squares:

c^{2} =a^{2} + b^{2}

Where:

c=34m

a=30m

b=?

So, by substituting we have:

34^{2}=a^{2} +30^{2} \\a=\sqrt{34^{2-}30^{2}}=16

Have a nice day!
