I believe the answer is 19.2 because you would have to do paythag. = a^2+b^2=c2 in this case it would be 7^2 + 10^2 = c
From there you would get the answer of 149, and you would have to square root it. When you square root 149 you get 12.2
12.2 + 7 = 19.2
You would add them together because you want to know the height before it broke.

Step-by-step explanation:

use phytagoras theorem to find the length of broken post

\sqrt{ {7}^{2} } +  {10}^{2}

\sqrt{49 + 100}

\sqrt{149}

= 12.2

add the broken post with the standing

= 7 + 12.2

=19.2
