Question

Q1.in fig the fig sides qp and rq of ∆pqr are produced to point S and T respectively.if angle SPR = 135° and angle PQR= 110° , find angle PRQ.​

Answer 1

Answer:

65

Step-by-step explanation:

<QPR=180-135

         = 45 (Linear pair)

<QPR + <PRQ=110 (Exterior angle theorem)

<PRQ=110-45

        =65

Answer 2

Answer:

PQR + PQT =180 (LINEAR PAIR)

110 + PQR =180

PQR= 70

PQR +PRQ=SPR

70 + PRQ =135

PRQ =135-70

PRQ=65
