18 points were scored by one figure skating pair that was 40% of your final score. what was the final score for that pair of figure skaters?

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

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.
