Question

Please help me and explain to me!

Answer 1

Explanation:

use phytagoras theorem to find the length of broken post

`\sqrt{ {7}^(2) } + {10}^(2)`

`√(49 + 100)`

`√(149)`

`= 12.2`

add the broken post with the standing

= 7 + 12.2

=19.2

Answer 2

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.
