mark me as brainliest

Answer 2

Question :

Construct a triangle PQR in which QR = 4.2 cm , Angle Q 120° and PQ = 3.5 cm. Draw PM perpendicular QR

Answer :

First of all draw QR with a scale.

Then construct 120 degree by drawing 60 degrees .

This way mark and join the other point of vertex.

Then draw an arc to QR.

Then construct the perpendicular by bisecting the length of the arc.
