Answer 1

You have to know this formula

Answer 2

So which answer choices can you eliminate

or have you figured out the final answer yet?

Look at the image I sent above

inscribed angle = ???

and then look at the second half of the answer choices

how would you write the equation for intercepted arcs?
(just multiply both sides by 2 to get rid of that 1/2)

Answer 3

My final answer is one half the measure of their intercepted arcs; m arc CDE= 2 ⋅ m∠CFE and arc CFE= 2 ⋅ m∠CDE

Answer 4

Which is C because quadrilateral CDEF is inscribed in circle A, so m arc CDE + m arc CFE= 360°. ∠CFE and ∠CDE are inscribed angles, which means that their measures are 1/2 the measure of their intercepted arcs. So, m arc CDE= 2 ⋅ m∠CFE and arc CFE= 2. m∠CDE.

Answer 5

Am i correct?

Answer 6

That is correct!
