Justifier que le triangle ACD est rectangle en D. Déterminer la longueur du segment (AC).
2. Déterminer la longueur du segment (EC).

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
