ajutor.Dau coronita....Multumesc

Answer 1

NQP triunghi drept - unghiul Q = 90grade
Pitagora
${np}^{2} = {nq}^{2} + {qp}^{2}$
${np}^{2} = {12}^{2} + {16}^{2}$
${np}^{2} = 144 + 256$
NP = 20
Teorema catetei in triunghiul MNP
${np}^{2} = mp \times qp$
400=MP * 16
MP= 25
MQ= MP-QP
MQ=25-16
MQ=9
Pitagora in triunghiul MNQ
MN = 15
