Given the equation
(x-3)^2+(y+7)^2=169, what is the radius of the circle? How do you know?

i don't see nikolas work.

step-by-step explanation:

6 cars because if you have 8 and subtract 2 youll have 6 left over

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.
