Gonna try to get this again... An irrational search (H) describe an irrational number that is bigger than 5.7 but smaller then 5.72.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

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.
