## anonymous one year ago If the measure of DEF is 65, what is the measure of ? http://media.apexlearning.com/Images/200701/18/df4742e6-e568-423e-bfe0-61f1985506e7.gif A. 65 B. 115 C. 32.5 D. 130

what is the measure of ?? whaT?

|dw:1440074251056:dw| i guess measure of blue part right ?

3. anonymous

is 32.5 for 130

4. Nnesha

DEF is an angle that formed by tangent and chord which is half of the measure of arc DE |dw:1440074363601:dw| to find DE $\huge\rm m<DEF=\frac{ 1 }{ }mDE$ m<DEF=65 solve for mDE

5. Nnesha

that supposed to be 1/2mDE

6. anonymous

ok

7. Nnesha

what is 32.5 ?

8. Nnesha

???

9. Nnesha

65 is an angle that formed by tangent and chord which is HALF of the measure of arc DE
