Figura alaturata reprezinta schita unui traseu turistic. punctele a, b si c sunt trei obiective turistice, d este mijlocul segmentului ab, de reprezinta un rau perpendicular pe segmentul ab. daca distanta de la b la c este egala cu 12 km si la o plimbare pe traseul a-e-c-a se parcurg 22 km, atunci distanta de la punctul a la punctul c este de??

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

length: 4cm

width: 9cm

height:   2cm

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
