Answer:

Concept:

The angle at F will be calculated using the formula below


\begin{gathered} \angle F=(1)/(2)(arcHE-arcGE) \\ arcHE=209^0 \\ arcGE=81^0 \end{gathered}

By substituting the values, we will have


\begin{gathered} \operatorname{\angle}F=(1)/(2)(arcHE-arcGE) \\ \operatorname{\angle}F=(1)/(2)(209-81) \\ \operatorname{\angle}F=(1)/(2)(128) \\ \operatorname{\angle}F=(128)/(2) \\ \operatorname{\angle}F=64^0 \end{gathered}

Hence,

The value of ∠F = 64°
