Kite DCFE is inscribed in circle A shown below. If the measure of is 232°, what is the measure of ∠ DEF? (5 points)

The measure of what is 232 deg? The info is missing in your post.

OpenStudy (anonymous):

I know that a circle = 360 and that 360 - 232 = 128 but 128 is the arc of angle FDE not DEF? I also know that the inscribed angles theorem means that angles = 1/2 the value of their intercepted arcs.

Oh oops hold on

OpenStudy (anonymous):

The measure of DEF @mathstudent55

OpenStudy (mathstudent55):

Angle DEF?

OpenStudy (anonymous):

Yes.

OpenStudy (mathstudent55):

Arc DEF?

OpenStudy (anonymous):

No angle DEF

OpenStudy (mathstudent55):

Wait. We are looking for the measure of angle DEF. That much I see in your post. What measures 232 deg? Is it arc DEF or something else?

The question is this: If the measure of ARC DE is 232°, what is the measure of ∠ DEF? I have shared an imagine. This is as much as I know: I know that a circle = 360 and that 360 - 232 = 128 but 128 is the arc of angle FDE not DEF? I also know that the inscribed angles theorem means that angles = 1/2 the value of their intercepted arcs.
