Question

In paralelogramul MNPQ , avem MN⊥ NQ si m(∡ MQN ) = 30° , NQ = 12 √ 3 cm . Calculati MN , MQ , MP . URGENT !

Answer 1

$sin(30)=\frac{MN}{MQ}=\frac{MN}{24}=\frac{1}{2},\,deci\,MN=12$$m(MQN)=30\, grade,\, deci\,\cos(30)=\frac{QN}{MQ}=\frac{12\sqrt{3}}{MQ}=\frac{\sqrt{3}}{2},\,deci\,MQ=24$
