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
