Question

Construct ΔPQR if PQ = 5 cm, m∠PQR = 105° and m∠QRP = 40°.

(Hint: Recall angle sum property of a triangle).

Answer 1

U can make this by Malkin angel of 40

Answer 2

its very simple
PQR +QRP+RPQ=180
105+ 40+ RPQ=180
145+ RPQ=180
RPQ= 180-145
RPQ= 35

LET DRAW A LINE PQ = 5CM

DRAW ANGLE P = 35°


DRAW ANGLE Q = 105°


FINALLY THEY INTERSECT EACH OTHER AT POINT R= 40°
