Question

Construct PQR if PQ=5cm,<PQR=105°and <QRP=40°.

Answer 1

first draw PQ 5 cm.Then draw angle PQR 105 degree
By angle sum property
sum of 3 angles is 180 degree
so,sum of angle Q ,R and P is 180
therefore,angle P will be 180 minus 105 plus 40
180 minus 145 is 35 degree
so,angle P is equal to 35 degree
then draw angle P
and at last measure angle R
