You survey people in a city to determine whether they support the construction of a new baseball stadium. The exact percent of all people in the city who support the construction of the stadium is likely between 65% and 70%. How many people did you survey? Round your answer to the nearest whole number.

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.
