Answer 2

Answer:

Let PQR is a right angled triangle.

PQ = 6cm, Angle RPQ = 60degrees = Angle P

tan 60degrees = QR/PR = √3 = QR/6 = QR = 6√3

sin 60degrees = QR/PR = √3/2 = 6√3/PR

= PR = 6√3 x 2/√3

= 6 x 2

= 12

Therefore, the length of QR is 6√3 centimetres.

Therefore, the length of PR is 12 centimetres.
