Question

In right angle triangle APQR, right angle is at Q and PQ = 6cms Z RPQ = 60°.
Determine the lengths of QR and PR.​

Answer 1

Answer:

you need to watch examples in text books

Answer 2

Answer:

tan 60 * = QR/PQ

root 3 = QR/6

root 3 ×6 = QR

$by \: \: pythgoras \: \: theorem$

PR^2 = QR^2 + PQ^2

PR^2 = 6 root 3^2 + 6^2

PR^2 = 108 + 36

PR^2 = 144

$pr = \sqrt{144}$

PR = 12 cm .
