Out of 125 children at summer camp 45 signed up for swimming 38 for arts and crafts if a child is randomly selected what is the probability that they signed up for swimming if it is known they did not sign up for arts and crafts

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.
