The hypotenuse of a right triangle has endpoints (2, 7) and (11, -5). What is the perimeter of the triangle

10

step-by-step explanation:

7+3=10

the answer is c. 23/3

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.

all of them are elements inside set of real numbers since none of them appears to have complex number form.

hope this .
