Final answer:
To find angle EBF, subtract the value of angle ABE from the value of angle ABF.
Step-by-step explanation:
To find angle EBF, we need to find the values of angle ABF and angle ABE first.
Given that angle ABF = 7b - 24 and angle ABE = 2b, we can substitute these expressions into the equation to find angle EBF.
Angle EBF = Angle ABF - Angle ABE = (7b - 24) - (2b) = 7b - 24 - 2b = 5b - 24.
