Question

In figure, sides QP and RQ of ∆PQR are produced to points S and T, respectively.

If ∠SPR = 135˚ and ∠PQT =110˚, find ∠PRQ .​

Answer 1

Answer:

45

Step-by-step explanation:

given:SPR=135,PQT=,110

SPR=PQT+QPR (an exterior angle is equal to two interior..)

135=110+QPR

QPR=135-110

QPR=25

PQR+QPR+PRQ=180( by angle sum property)

110+25+PRQ=180

PRQ=180-135

PRQ=45
