Natalie has two number pyramids each labeled 1 to 4. natalie is going to conduct an experiment by tossing both pyramids a total of 96 times. she will find the difference of each pair of numbers rolled by subtracting the lesser number from the greater number.

step-by-step explanation:

it is a horizontal line.

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.
