What expression can be written to represent the sum of the angle measures?

add 8+12 to get a simplified answer of 12r-20

i think the answer is a.( -3, -1 )

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
