Prove:
<D=<B
Statement Reason
------------------------------------------------------------------------
AC bisects <BAD and <BCD | Given
m<DAC=m<BAC | Definition of an angle bisector
m<CAD=m<CAB | Definition of an angle bisector
AC=CA | Reflexive Property of Congruence
△ACD=△ACB | ASA
m<D=m<B | CPCTC
Answer:
The value of given expression is 0, where m=21 and n=12.
Step-by-step explanation:
The given expression is
substitute m=21 and n=12 in the above expression.
Therefore the value of given expression is 0, where m=21 and n=12.
