Question

(i) In right-angled triangle PQR, if ZP = 60°, ZR = 30° and
PR = 12, then find the values of PQ and QR.​

Answer 1

IN TRIANGLE {PQR}

ANGLE. P=60°

AND ANGLE R=30°

SIDE OPPOSITE TO 30° PQ =½×HYPOTENUSE

= ½×12=6

SIDE OPPOSITE TO 60° QR =½×HYPOTENUSE

=√3/2×12=6√3

THEREFORE. PQ=6 AND QR=6√3
