Explicație pas cu pas:
MQ⊥NP⇒∠MQN=90°⇒ΔMQN dreptunghic in Q
Aplicam teorema lui Pitagora in ΔMQN ⇒ MQ²+QN²=MN²⇒MQ²=MN²-QN²⇒MQ²=36²-21,6²⇒MQ²=1296-466,56⇒MQ²=829,44⇒MQ=√829,44⇒MQ=28,8
MQ=28,8 cm
MQ²=NQXQP ⇒829,44=21,6XQP⇒QP=829,44:21,6⇒QP=38,4
QP=38,4cm
PN=QP+NQ⇒PN=38,4+21,6⇒PN=60
PN=60cm
ΔMNP dreptunghic aplicam teorema lui Pitagora MP²+MN²=NP²⇒MP²=NP²-MN²⇒MP²=60²-36²⇒MP²=3600-1296⇒MP²=2304⇒MP=√2304⇒MP=48
MP=48cm
