Question

Side QR of A PQR is extended on both the
sides so that exterior angles Z PQS and Z PRT
are formed. If Z PQS = 100° and Z PRT = 130°,
=
find the measure of each angle of A PQR.

Answer 1

Step by step explaination:

Here Angle PQS=100°

Angle PQS+ Angle PQR =180° (it is forming a linear pair)

100°+ Angle PQR =180°

Angle PQR = 180°-100°

ANGLE PQR = 80°
