Answer:
FI = 48
Step-by-step explanation:
We know that FI and IH are equal. so we can build an equation to solve this tricky and messy question which tries to scare you by giving additional information.
z + 22 = 4z -56
z - 4z = -56 - 22
-3z = -78
z = -78 / -3
z = 26
so we know FI = z + 22
= 26 + 22
= 48
