Question

plsss dauuuu coroanaaaa​

Answer 1

Răspuns:

Fiindca stim proectiile, putem afla ipotenuza:

PR=MR+MP =>PR=12+3=15

Ca sa aflam catele, putem folosi teorema catetei:

$QR^{2}$=MR x PR

QR=$\sqrt{12 ori15}$

QR=$\sqrt{180}$

QR=$6\sqrt{5}$

$PQ^{2}$=PM x PR

PQ=$\sqrt{3ori15}$

PQ=$\sqrt{45}$

PQ=$3\sqrt{5}$

Acum ca am aflat catetele, putem afla pe QM astfel:

QM=$\frac{QRxQP}{PR}$

QM=$\frac{6\sqrt{5} x 3\sqrt{5} }{15}$

QM=$\frac{18x5}{15}$

QM=$\frac{18}{3}$

QM=6

Sper ca te-am ajutat!!
