Question

In a triangle PQR, side QR is produced to S such that <PRS = 140°. If <P = <Q, then <Q is equal to

70°

40°

60°

35°

​

Answer 1

Answer:

70 °

Step-by-step explanation:

angle PRS=140°

QRS is a straight angle

straight angle= 180 °

so

PRS-QRS

180°-140°= 40°

angle R= 40 °

so

∆le PQR=180°

angle R= 40°

180°-40°=140°

angle P=angle Q ( given )

140°\2=70°
