Answer:
109
Step-by-step explanation:
Formula
<ZHG + <IHZ = <IHG
Givens
<ZHF = 11x - 1
<IHZ = 24
<IHG = 12x + 13
Solution
11x - 1 + 24 = 12x + 13 Combine terms on the left
11x + 23 = 12x + 13 Subtract 13 from both sides
- 13 - 13
11x + 10 = 12x Subtract 11x from both sides
-11x -11x
10 = x
Answer
11x - 1 = 11*10 - 1 = 110 - 1 = 109
