When Dracula finished the next level of his video game he won 65 points for fast level completion and lost 80 points for each of the three targets he missed write the total change to his score as an integer

the correct answer is the second option

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.

depends what are you allowed to do ?
