The driving distance from Los Angeles to a Chicago is 2,054 mi. The distance from Chicago to Boston is 983 mi. About how many miles is the drive from Los Angeles to Boston though Chicago?

Step-by-step explanation:

given :

The driving distance from Los Angeles to a Chicago is 2,054 mi. The distance from Chicago to Boston is 983 mi.

so, the numbers of mile driving from Los Angeles to Boston though Chicago =

2,054 + 983 = 3.037 mi

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
