Question

in figure 2.7 line l parallel line m and line in parallel line find Angle A Angle B and angle C from the given measure of an angle 45 degree​

Answer 1

HERR IS YOUR ANS.

angle BRT = 105° (GIVEN)

PRB = 180°- BRT = 75°

BY(linear pair angle)

PRB = ART = 75° (ALTERNATE ANGLES )

BRT = DTQ = 105° (correspondence angle)

ART = CTQ = 75( by corresponding angle.)

hope it helps..
