Question

construction a triangle PQR angle Q= 60° angle R= 30° PQ+QR+RP = 12.5 cm
​

Answer 1

hope it helps
mark me brainiest

Answer 2

CONSTRUCTION OF ΔPQR WITH ∠Q = 60° AND ∠R = 30° AND

PQ + QR + RP = 12.5

• Draw a line segment AB = 12.5 cm.
• Construct angle 60° at point A and angle 30° at point B.
• Draw angle bisectors to angles A and B.
• Let these angle bisectors intersect at point P.
• Draw perpendicular bisector to line segment AP.
• Let this bisector meet AB at Q.
• Draw perpendicular bisector to line segment BP.
• Let this bisector meet AB at R.
• Join PQ and PR.
• PQR is the required triangle.
