Let us return to the original question concerning whether high incidences of cancer in some area can be attributed due, simply, to random fluctuations or to some other, possibly environmental, factor. The number of cancer diagnoses per year in ten cities, each with a population of 100,000 people, is the only information provided to you to determine this. First, what is the average number of cancer diagnoses per city per year

step-by-step explanation:

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.
