OpenStudy (anonymous):

OpenStudy (mathstudent55):

The two radii are congruent, so opposirte angles are congruent.

OpenStudy (anonymous):

c'mon @marissalovescats (future math teacher) name the other two angles in the triangle!

OpenStudy (mathstudent55):

An arc has the same measure as the central angle that intercepts it.

OpenStudy (marissalovescats):

I made an A- in Geometry soo nothing is really retained XD

OpenStudy (anonymous):

according to law of sines, < DAB = 48° also. this means that < ADB = 180 - 48 - 48 = 84°

OpenStudy (anonymous):

OpenStudy (anonymous):

48

OpenStudy (anonymous):

OpenStudy (anonymous):

@marissalovescats I have to say you're the smartest girl I know :p

OpenStudy (marissalovescats):

Eh.. That's probably definitely an understatement. Hahaha

OpenStudy (anonymous):

I must say it's a true statement (:

OpenStudy (anonymous):

OpenStudy (marissalovescats):

Me either. ^^^

Refer to what "mathstudent55" said: An arc has the same measure as the central angle that intercepts it.
