In a certain country, the life expectancy of a man born in 1999 was 79.1 years. In 2009, the life expectancy was 0.6 years greater. If L represents the life expectancy of a man born
in 2009, what equation could you use to find the value of L? Use pencil and paper. Could two
different equations be used to find the value of L?

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

0.038

step-by-step explanation:

answer: as the alternate interior angles are congruent, the opposite

sides of quadrilateral abcd are parallel.

step-by-step explanation:

so, the missing phrase in elba's proof is: alternate

interior angles

let's break this statement up so we can find the answer:

by cpctc, angle abd is equal to angle cdb and angle adb is

equal to angle cbd.

since

angle abd is equal to angle cdb, this means that they are alternate interior angles

so, the correct answer would be: as the alternate interior angles are congruent, the opposite

sides of quadrilateral abcd are parallel.

two interior angles which lie on opposite sides of a

transversal   and on different parallel

lines and are called alternate interior angles.
