Question

produced to point s and t respectively. ​

Answer 1

Answer:

135 + RPQ = 180. (LINEAR PAIR)

RPQ = 180 - 135 = 45°

RPQ + PRQ = 110° (EXTERIOR ANGLE)

PRQ= 110 - 45 = 65° ANSWER...

Answer 2

Answer:

angle SPR + angle RPQ = 180 ( linear pair )

135+ angle RPQ= 180

angle RPQ = 180°-135°

angle RPQ =45..........(1)

angle PQT. + angle PQR= 180 ( linear pair)

110 + angle PQR = 180

angle PQR= 70°.........(2)

in∆ PQR

angle P+ angle Q+ angle R= 180. {angle some property of ∆}

45°+ 70° +R= 180°

115° + R= 180

Angle R= 65°

hence angle PRQ = 65°
