I’m still confused on how to do this even though it was explained to me please help :(

Answer 1

$a. \: \hat{D}=\hat{C}=64° \\ b. \stackrel\frown{BF}=2\hat{C}=2\times 64°=128° \\ c. \: \hat{E} = \hat{C}=64° \\ d. \stackrel \frown{CBF} = 2\widehat{CEF}=2\times 90°=180° \\ e. \: \widehat{BAF} = 2\hat{C} = 2\times 64°=128° \\ f. \: \widehat{BAC} = \widehat{CAF}-\widehat{BAF}=180°-128°=52°$
