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.

\sqrt{149}

= 12.2

add the broken post with the standing

= 7 + 12.2

=19.2

Please help with this question. I need an answer ASAP!! I need help! I don't understand this!
Romashka-Z-Leto [24]

Answer: 42°

<u>Step-by-step explanation:</u>

HJ is an angle bisector of ∠IHK so

∠IHJ ≅ ∠KHJ ⇒ m∠IHJ = m∠KHJ

                           3a + 6 = 5a - 18

                                   6  = 2a - 18

                                  24 = 2a

                                   12 = a

∠IHJ = 3a + 6

        = 3(12) + 6

        = 36 + 6

         = 42
